SOG marks four decades with a limited, 500-piece run honoring its original MACV-SOG combat bowie root.
To mark four decades in business, SOG Knives has released a limited-edition homage to the blade that started it all: the 40th Anniversary Fat Guard Bowie. Drawing direct design cues from the original S1 Bowie introduced in 1986, the new release pays tribute to the covert fighting knives carried by MACV-SOG personnel during the Vietnam War.
Historical Roots, Modern Production
The 40th Anniversary model centers around a 6.1-inch clip-point blade forged from AUS-8 stainless steel. SOG finished the steel with a black PVD coating for added corrosion resistance and reduced reflection.
True to the traditional combat bowie silhouette, the handle is built from stacked leather, offering a classic aesthetic alongside a contoured grip. A substantial brass guard and matching butt cap frame the handle assembly. Production is strictly capped at 500 individually serialized units, with each knife’s specific number etched directly into the pommel.
Commemorative Display Package
Rather than shipping as a standalone tool, SOG packaged the anniversary Bowie as a complete collector’s set. The knife sits inside a handcrafted pine display case outfitted with a clear glass viewing lid and an engraved anniversary plaque.
Accompanying the fixed blade inside the presentation box is a custom SOG 40th anniversary Zippo lighter and a signed certificate of authenticity. For field carry or storage, the set includes a heavy-duty black leather belt sheath, complete with a front-mounted snap pocket containing a touch-up sharpening stone.
The 40th Anniversary Fat Guard Bowie package is available directly through SOG’s website while supplies last.
Timeless and iconic, it remains practical and complementary to other options today.
The novaculite sharpening stone is a wonder of nature. Almost pure microcrystalline quartz in content, this dense, fine-grained rock was formed from 318 to 416 million years ago during the Devonian and Mississippian periods in ancient seabeds and later pushed toward the surface with the peaks of the Ouachita Mountains of western and central Arkansas. Massive sedimentary layers ranging from 250 to 900 feet thick produced the stone, which takes its name from the Latin novacula, meaning “sharp knife” or “razor.”
From there, the stone was destined for a rendezvous with the knife blade, rendering a sharp edge that gets the job done and holding a place in working knife history dating back centuries.
The novaculite deposits in Arkansas were formed 318 to 416 million years ago and it takes plenty of mechanical muscle to push around the material. The deposits run from 200- to 900-feet thick, in turn the operations are substantial. And while the weathered novaculite is somewhat bland to the eye, once broken up the beauty of the natural material shines through. (Images courtesy of Chis Stillian)
Today, however, there is a bit of … well … friction as some may claim modern synthetic stones are eclipsing or at least competing with novaculite for some nebulous title of “best.” Synthetic stones often offer faster sharpening and convenience, while novaculite is valued for its refined finish and traditional appeal. Truth is that each has its place, and novaculite was and is a key participant in the knife-sharpening exercise.
“It gives a razor-sharp, polished edge with smooth feedback that many prefer over synthetics,” explained Chris Stillian, owner of Natural Whetstone, LLC. The company was founded by close friend David Davenport two decades ago, and when David passed away during the COVID-19 pandemic, Chris and his father, Shawn, kept the central Arkansas company going.
“The stones wear very slowly,” Chris continued. “Some last decades because they’re 99 percent plus pure quartz with no fillers. They’re natural, made in the USA and work great for chefs, woodworkers and knife users.”
Danny Kirschman founded Dan’s Whetstone Company, Inc., in Pearcy, Arkansas, in 1976, and his son Steve is currently CEO of the family venture. His roots in novaculite are long and deep. “The erosion-resistant quartz formations of the Ouachitas produced the finest and rarest natural abrasive in the world,” he offered. “Danny Kirschman’s opinion and what we share with others is that the one thing that sets novaculite products apart from other sharpeners is their unique crystalline structure. The novaculite stones wear less aggressively than most manmade abrasives due to the natural bonding of the crystals.”
Best Steel For Novaculite
Dan Kirschman, by the company’s largest saw, spent his formative years as a mining engineer, until his hobby of cutting and polishing novaculite developed into a full-time business. Dan’s Whetstones now has a 500-acre quarry and manufactures more than 300 different products from the stone. (Images courtesy of Dan’s Whetstone)
Both Stillian and Kirschman agree that the disadvantages of novaculite usage lie in cutting speed and other aspects. Chris commented, “It cuts slower than diamond or water stones, so it’s better for refining edges than heavy profiling. It needs oil instead of water, can glaze if not cleaned and doesn’t bite hard on modern super steels. Top grades cost more because the dense material is rare.”
Steve added, “The most common complaint is their low abrasion rate. Because the stones are exceptionally hard and dense, they remove material much more slowly than synthetic stones. They are best suited for maintaining an already sharp edge rather than ‘hogging off’ metal to repair chips or reprofile a blade. There is no truly coarse Arkansas stone. Even the soft Arkansas is relatively fine compared to a coarse synthetic stone. Novaculite is composed of quartz, which has a Mohs hardness of around 7. While this is harder than standard carbon steel, it is softer than the vanadium and chromium carbides found in modern, high-alloy super steels.”
Further, since Arkansas stone is a natural product, every stone is unique and may exhibit internal flaws, cracks or variable grit. Oil is required to keep metal particles, or swarf, from clogging the pores, which leads to a bit more cleanup. Lubrication keeps the stone from “loading” with metal, which can reduce its effectiveness.
Similar to many sharpening systems, Arkansas stones of different grit sizes are used in conjunction. On the right is a soft stone with a courser grit, good for raising a burr and initial honing. On the left is hard stone, used for final edge polishing and day-to-day maintenance. (Image courtesy of Chris Stillian)
Novaculite works best with simple carbon and low-alloy stainless steels like 1095, O-1, 440C and A2. Since such steels are commonly found on hunting, working, kitchen, bushcraft/survival and everyday slipjoint and fixed-blade knives, a broad area of application exists. High vanadium super steels such as S35VN, M390, CPM-3V and others—often seen in premium chefs’ knives and high-end custom knives—are best served with diamond stones, for example, because their carbides are harder than the quartz in novaculite.
Reviving Arkansas Rock
Even the casual observer can, therefore, discern the proper employment of the novaculite sharpening stone with the blade steel that will produce the best results. One giant of the knife industry recognized the value of the Arkansas stone years ago and built a catalog empire on its sturdy reputation.
The late BLADE Magazine Cutlery Hall of Fame® member A.G. Russell began selling Arkansas sharpening stones in the mid-1960s after moving his family back home to northwest Arkansas from Marin County, California. During the move, he discovered that his whetstones had gotten lost in transit.
Novaculite is microcrystalline quartz in structure and while it can seem extremely smooth to the naked eye, at the microscopic level the formation’s cutting properties become evident. On the left is ultra-fine black stone at 5000x magnification and the right hard Arkansas stone at 2500x magnification. (Image courtesy of Dan’s Whetstones)
“He tried to buy replacements in local hardware stores, but none stocked them,” remembered A.G.’s wife and fellow hall-of-famer Goldie Russell, who runs the company today. “Having lived in Hot Springs, Arkansas, for a while when he was a teenager, A.G. knew that the only deposit of novaculite was in that area. A.G. went to Hot Springs and found someone who was cutting stones. He purchased stones and began selling them to local hardware stores.”
From there, A.G. bought ads in magazines, particularly Guns & Ammo and The American Rifleman. Soon enough, he became a supplier to Brownells, a major gun retailer, capitalizing on the mutual affinity of gun enthusiasts for knives. Together with the magazine effort and his own sales acumen, Russell re-energized the popularity of the Arkansas stone.
“The frequency of A.G.’s ad in magazines and then the offering of these stones in the A.G. Russell Catalog of Knives was very important in making these stones readily available nationwide through the late 1960s and the 1970s,” observed Goldie. “There is still a large quantity of the small stones that he had cut during those years in our inventory. That is how he started what became A.G. Russell Knives.”

Novaculite stones, therefore, maintain their place in the practical and the historical aspects of the knife industry, and their relevance is not likely to fade. Those who are familiar with their capabilities remain loyal. They appreciate the investment of time and effort required to bring out that razor-sharp edge, and there is something timeless and reaffirming in the process.
Novaculite Grades
The stones themselves are available in four major grades. “Users should be aware that color is not the determining factor in grading novaculite,” explained Kirschman. “Some users have been defining whetstone grades by color, but the same colors may be seen in more than one grade. Color is caused by trace minerals that are dispersed through the rock during sedimentary formation more than 350 million years ago and subsequent geological activity.”
The major grades of novaculite include the following:
Soft Arkansas: The most popular all-purpose stone often used by wood carvers, sportsmen, butchers, commercial knife sharpeners and even housewives who desire keen, polished edge in a minimum of time.
Hard Arkansas: A fine grit stone good for everyday maintenance and popular among woodcrafters and the dental industry.
Translucent and True Hard Arkansas: An extra fine stone with a glassy feel and used in industrial applications requiring an extremely fine polish. It appears in a variety of colors.
Black Arkansas: Sometimes referred to as “surgical black” stone, the finest grade abrasive available today, delivering a mirror polish.
Among the most critical factors of using natural stones to sharpen knives is using honing oil. Oil keeps metal particles, or swarf, from clogging the stone’s natural pores, thus reducing its effectiveness. (Image courtesy of Chris Stillian)
The proper method of sharpening with a novaculite stone involves preparation and practice. “It’s an oil stone, so put a few drops of honing oil on it,” advised Stillian. “Hold a consistent angle, 15 to 20 degrees for most knives, use light to moderate pressure, and take smooth strokes. Start on soft or hard if the edge is dull, and finish on black or translucent. Raise a burr, then lighten pressure. Clean with soap or solvent to avoid glazing. Strop afterward for extra keenness, if you like.”
Those About To Rock
According to Chris, consistent purchasers and users include enthusiasts, woodworkers and chefs who “keep buying them for the feel, longevity and heritage. Synthetics rule high-volume work, but real Arkansas novaculite—especially the rare translucent and black grades—still sell at a premium to people who want the genuine article.”
Steve sees emerging interest as well. “The rising D.I.Y. (do it yourself) sharpening culture is a major driver,” he commented, “with the hobbyist segment now accounting for nearly 35 percent of total whetstone sales worldwide. Online tutorials and a deeper appreciation for craftsmanship have fueled this demand. Sustainability is a driver, as well. Modern consumers increasingly view natural stones as a “green” alternative to synthetics.
“Niche premium positioning, even while high-end market saturation is slowing growth in North America to about 4 percent, means natural stones remain a staple for professional chefs who prefer them for maintaining blade integrity,” Steve concluded. “And technological integration means that manufacturers are now developing beginner-friendly kits and instructional digital content to tap into 62 percent of home users who are interested in traditional sharpening but lack confidence in the technique.”
The future presents an atmosphere of coexistence among the Novaculite and synthetic options. The global whetstone market topped $457 million in value in 2024 and is expected to reach $677 million within eight years. Natural stone demand should stay steady, supported by its faithful and traditional users while welcoming explorers to these Ouachita wonders.
The popular pattern offers a complex combination of material and motif.
The variations on damascus steel themes are endless. The possibilities are tempered only by the maker’s time at the forge and his or her desire to create.
Among these many variations, one pattern has recently captured the spotlight. These days, feather damascus is trending and custom makers are producing knives that turn heads, captivating buyers with the intricate layering that produces hard steel intertwined with the look of the light and wispy. Feather damascus offers a medium of both performance and artistic expression that influences every aspect of the maker’s creativity.
Ethan Kolar of Plummer, Idaho, describes his interest in feather damascus as “chaotic flow.” He explains, “The pattern’s center seam, where the jagged W’s converge, creates a flow in the blade which really adds to the overall confluence of the knife as well as creating a controlled chaos as the pattern explodes from the center filling out the blade.”
Kolar enjoys the hint of “jaggedness” and the center line that ties the blade together, and in the making of his feather damascus, his focus lies in test etching every restack from the forge. He sees the pattern in many different forms with the observation that “a pattern is not right or wrong but more of what the maker envisions and creates and what is right to him for his knife.”
The folding dagger Ethan composed includes a 3-inch feather damascus blade of 1084 and 15N20 steels with an engraved gold inlay and scroll worked 416 stainless steel window frame fitted with exhibition-grade white-lip mother of pearl. Liners are 15N20 file-worked and nitre blued, while the backbar of 416 stainless is engraved and sports delicate file work. Its overall length is 7 inches.
“Most of the inspiration I have while making damascus comes from envisioning my final product,” Ethan remarked, “what engraving will go with it, the handle embellishment, and a lot to do with the overall color of the knife, deciding whether the pattern will be brighter or darker.”
Steel On Fire
Winning Best Damascus at the 2025 BLADE Show West, Trevor Morgan’s “Torrent of Fire” chef’s knife includes a 9.25-inch blade of 1084 and 15N20 in a mix of W’s and straight layers with a fat core of 15N20. The knife’s overall length is 14.2 inches, and the handle is dark red tiger’s blood amboyna burl with a splash of sapwood for contrast. (Jocelyn Frasier image)
Another contemporary artisan exploring the feather damascus pattern is ABS journeyman smith Trevor Morgan. Having attended the Bill Moran School of Bladesmithing in Texarkana, Texas, in 2020, his goal with each feather damascus blade is to make the pattern “pop.” To achieve that look, his hand follows an artistic eye.
“Contrast, for sure, really makes any pattern cool,” said Trevor, “especially feather or mosaic damascus, larger pieces of dark and bright steel, gradients and that kind of thing. Also, out-of-the-ordinary stuff like feather [damascus] can be really cool to look at. Symmetry is always great with a feather pattern because it’s pretty easy to notice when something is out of whack with a feather due to the defined center. Complexity is also great. If it’s hard to figure out, all the better.”
According to Morgan, a resident of Apple Valley, California, the feather pattern can be challenging due to the hot-cut process, which puts enormous stress on the billet in somewhat weird ways and causes every forge weld to want to split open. The problem, however, can be mitigated by mig welding all the way around the seams. But this is his least favorite method of achieving the integrity of the billet because it requires grinding away the welds, wasting material and consuming time.
Trevor’s inspiration for feather damascus pieces comes from the world around him. “It’s places and people,” he commented, “from nature and the endeavor to make something organic and as lifelike as possible in steel. I regularly get swept up in the general zeitgeist surrounding the making of complex patterns. I see something on social media or somewhere, and I think, ‘Man, that’s really awesome! I’d love to try to make something like that.’ Then comes the real creative part, where I just get an idea of something that might look really cool and put it together.”
Morgan’s method is readily revealed in his featured piece, named “Torrent of Fire.” The knife includes a 9.25-inch blade of 1084 and 15N20 in a mix of W’s and straight layers with a fat core of 15N20. The knife’s overall length is 14.2 inches, and the handle is dark red tiger’s blood amboyna burl with a splash of sapwood for contrast.
Organic Appeal

Feather damascus has been a staple steel for ABS master smith Steve Randall for some time. He seeks a continual flow of the steel from the handle to the tip, and oriented so that the handle appears to actually hold a feather. “I was attracted to the feather pattern because of it’s a very cool, organic look,” he advised. “Like a snowflake, there are no two exactly the same. I’ve been forging feather damascus for at least seven years, and I’ve made several bowies and hunters.”
Randall, of Estancia, New Mexico, presents his feather damascus piece with frame-handle construction, showcasing mastodon scales with an overall length of 9½ inches and a blade of 4¾ inches. “Feather damascus is a more challenging pattern,” he said. “My tricks are patience and concentration. There are many welds involved in the pattern, which can contribute to cold shuts, which can destroy hours of hard work. The trickiest part is splitting the billet right down the middle and maintaining symmetry.”
While he describes the feather damascus forging process as complicated and labor-intensive, Steve sees the payoff in the harmony of the pattern and its related materials in the finished knife. “I always try to complement it with the best handle materials I have available,” he reasoned. “I prefer stag or ivory. If using wood, I avoid busy patterns and colors. I draw inspiration from many other makers. There are so many accomplished makers who produce a variety of feather patterns. It is one of my favorite patterns to forge because it can really accent the flow of the blade and give it a great overall look.”
Movement And Flow
While David Lisch doesn’t feel he’s hit the limits of his Mountain Man folder, the style of knife is striking with its feather damascus blade set in stag-tip handle. Copper hardware and pivot give the knife its antediluvian look, while the flowing pattern of the blade anchors it in modern forge techniques. (David Lisch image)
It took a single demonstration by the great master smith Harvey Dean to convince David Lisch, who earned his ABS journeyman stamp in 2009 and his master stamp six years later, to try the feather pattern. “I was always attracted to feather damascus,” he remembered, “but around 2008 I had the chance to see Harvey Dean demonstrate it at an event at Josh Smith’s, and I went right home and made the tools needed and gave it a go. I’ve been making feather damascus since his demo, and my hat is off to Harvey.”
For David, the making of feather damascus is challenging, but he says book matching the blocks really helps with the constant flow of the pattern. Sometimes, he says, makers will intentionally disrupt the flow by spinning one block one way and one the other to enhance the look. If it is done intentionally, he advises, there is no wrong way to stack the blocks. Forging all begins with the initial stack, and David starts with a 12- to 15-pound billet, acknowledging that the pattern can be wasteful in material. He tries not to go too far or stop too short in the forging process and offers that sometimes less is actually more.
“I love feather damascus because it looks different from maker to maker,” added Lisch. “I like a feather with movement and flow, not too bold and not way too fine, something that is easy to look at. For me, the more the pattern follows the forging, the more I like it. The center should lift up into the bolster or ricasso, showing that the blade was forged rather than running off the blade under the ricasso, showing it was just ground into a shape that disrupts the flow.”
Lisch gained a measure of popularity with his Mountain Man 2 folder, and the pictured knife is an example of what he describes as a “deep dive” into the style while using stag tips. “I set out trying to create my own version of one of the oldest knife designs in America,” he remarked, “and I believe I did just OK. But I’m not finished. So far, I’ve made several versions of the folder and have taken it even further with help from my friend and mentor [master smith] Mike Vagnino.”
Lisch had brought together his feather damascus touch and innovative design composition by introducing a clocking adjustable pivot that he has incorporated into a slipjoint, linerlock, lockback and flipper, all in the Mountain Man style with bronze, copper, stag and, of course, feather damascus. He has yet to reach the outer limits of his Mountain Man creativity and says that more will come in due time.
Engineered for upland hunting and fine-detail game prep, Civivi’s latest fixed blade puts precision first.
Civivi is expanding its lineup of dedicated field tools with the High Grass Field Knife, a compact fixed-blade built specifically for upland hunters and small-game processing. Designed by Michigan custom knifemaker Matt Gentry, the production model translates years of hands-on experience in Michigan’s Upper Peninsula into an accessible, purpose-built knife where fine control takes priority over raw size.
The inspiration for the High Grass stems directly from Gentry’s time spent pursuing small game with his son across Michigan’s northern terrain. Rather than modifying a general-purpose camp knife, Gentry set out to build a nimble tool optimized for delicate field-dressing tasks of fowl and small game.
To achieve that level of precision, the knife features a 2.93-inch drop-point blade with a flat grind and an ultra-fine tip, making detail work around joints and skinning far more manageable. Dual sections of jimping along the spine provide tactile indexing points, allowing users to safely choke up on the blade for tight, controlled cuts.
Field-Ready Materials
Civivi opted for Sandvik 14C28N stainless steel for the blade stock, heat-treated to 58–60 HRC. The steel offers a solid balance of edge retention, corrosion resistance and ease of resharpening in the field. A stonewashed finish helps mask the inevitable scuffs and scratches that come with regular use.
For the handle, natural Guibourtia wood scales offer a classic look that honors traditional hunting gear while maintaining a comfortable, ergonomic fill in the hand. Stainless steel hardware keeps the construction secure, and at an overall length of 7 inches with a weight of 2.26 ounces, the knife carries light on a belt or in a pack.
The High Grass Field Knife ships ready for the field with a molded black Kydex sheath. The setup features a T-Clip mounting system designed by knife industry veteran and BLADE Magazine Cutlery Hall of Fame® member Bob Terzuola, providing versatile attachment options for belts or pack webbing. A pre-tied black paracord lanyard comes installed from the factory for added draw leverage.

Whether you need a pristine edge for skinning game or a razor-sharp utility blade for daily EDC chores, it is easy to see why replaceable-blade knives have exploded in popularity. Chaves Knives takes this a step further.
The Pleasant Grove, Utah, manufacturer is known for thinking outside the box with its designs and this holds true for its CHUB. A very fast out-the-front (OTF) double-action small pocket utility knife ensures you never have a dull blade, can get it into action no matter what the circumstances,and is fun. Even so, the knife must perform, so let’s see if the CHUB cuts it.
Expected from most utility knives, the Chaves model ate up cardboard in the course of testing. It was quick work, but for the author, somewhat challenging given the CHUB’s smaller handle.
I started with a standard paper slice to test the factory edge on the replaceable blade. I used graph paper and, as expected, the CHUB’s edge zipped through it quickly, producing clean slices and smooth cuts. The knife’s handle was comfortable, even though it was a tad short for my hand.
Onto single-walled cardboard, the CHUB burned through the medium. I could get used to this performance, as I break down cardboard daily. No folding or sliding, just an aggressive in and out through the material. The handle provided a positive grip, a plus on the more challenging cardboard. As a note, the knife rides very nicely in any pocket.
Slapping Leather
The author figures leatherworkers might find the knife very handy as it proved aggressive against leather. Given its fast deployment, it’d be very suitable in this role.
I grabbed a leftover piece of 8-ounce leather to shred. The CHUB was very aggressive on the hide. Vertical slices were fast and easy to control, and with the leather flat on the bench, it sliced through smoothly. If you happen to work with leather, it would be a great job for the CHUB.
Pitting a blade against wood is always a must, so I moved on to some whittling. A ¾-inch dowel proved no problem for the CHUB. The replaceable blade shaved smooth curly cues, but deeper bites were harder on the hand because of the smaller handle. Still, it got the work done.
Pitted against a ¾-inch dowel proved no problem for the utility blade, wich shaved smooth curly cues and made deep bites into the wood.
Just to push the knife a little farther, I cut up some ½-inch sisal rope. The CHUB did 125 crunching cuts, which was impressive, given it was the same blade I started the test with. The action stayed tight and crisp, no play at all. Again, the handle size was challenging in a task that required stronger pressure. But overall, it was a fun challenge.
Lastly, I was back to the graph paper slices. I had a few snags at the bottom of the blade but the front half sliced smoothly. Not bad at all. Job well done by the Chaves Knife crew. I also still had a fresh edge, since all I had to do was push a tab over, flip the blade and close the tab. Pretty simple and fast.
Overall Take
The CHUB rides comfortably in any pocket, according to the author. Helping with it in this task is a clip with Chaves’ trademark skull.
Some people might call it a fad, but the CHUB will cut. Now add in the cool factor of it being an OTF pocket utility knife, and you have a handy knife to use daily. The CHUB is designed to take standard Stanley and Lenox-style blades—2 7/16-inch long, ¾-inch wide—but off brands might not prove compatible.
These veteran-designed or manufactured knives are ready to serve.
A rare combination, military knives aren’t simply utilitarian tools; they stir something deep inside of us. Whether an inborn call of duty or a profound respect for those who served, edged implements meant for battle call to knife aficionados with a patriotic streak. Which, simply put, makes them wildly hot in the eyes of manufacturers and collectors alike.
Not all military knives are issued. Some of the most storied were picked up as “just in case” purchases at post PXs or sporting goods stores throughout the years. This doesn’t make them any less ready to serve. And, today, there are a slew of options engineered or built by veterans, meant for action—in the field of battle and for everyday protection and chores—and more than able to cut muster.
Winkler Knives Operator
At first glance, the Winkler Knives Operator seems like the average utility fixed blade or a larger bird and trout knife. Looks can be deceiving as the Operator functions both as a utility tool and weapon—important in the theater of battle.
Originally founded to produce specialized breaching tools at the request of the SOF community, Winkler Knives of Blowing Rock, North Carolina, is certainly no stranger to tactical knives. Their Operator series offers a unique design that is a crossover of sorts. Yes, it was designed as a tactical knife, yet has proven popular as both a camp, general outdoor and hunting knife.
Designed by former Navy SEAL Kevin Holland, the Operator features a 4⅛-inch-long clip-point blade made of 80CrV2 tool steel and given a black oxide coating for rust protection. This steel is an excellent choice for a multi-use knife as it is resistant to impact and holds an edge reasonably well. When it’s time to resharpen, most are pleasantly surprised by how quickly the edge comes back with basic manual sharpening equipment. Given that the blade tapers to a sharp point, it excels as both a weapon and a tool. It has excellent penetration qualities and the thick stock, combined with a flat grind, allows the blade to slice with little resistance.
The Operator’s handle is very well designed, facilitating an excellent grip—a rarity on many compact fixed blades. A subtle finger groove helps index your grip and a flare at the butt and slight downward turn secures the hand from sliding backwards. All the edges on the grip are rounded for maximum comfort and the Operator certainly feels good in hand. I evaluated the antique maple-finished handle for this review. Other materials are available, including Micarta. As to the wood version, it feels warm in the hand, secure and the grain gives a nod to being like a fine furniture.
The Winkler Knives Operator isn’t afraid to tackle delicate cutting tasks. It easily sliced Styrofoam packing peanuts, a testament to how well the blade is engineered with its distal taper spine, full height flat grind and razor-sharp factory edge.
Standard with the Operator is a formed leather sheath, designed and made by DeSantis Gunhide, specially for Winkler Knives. It has a set screw to control the tension on the knife so you can customize the retention—a nice touch, not often offered. As for carry, there is a fold-over metal belt loop affixed with two screws, facilitating traditional outside-the-waistband and pocket carry. The latter leaves the handle sticking out for quick access.
Overall, I love how the handle feels in-hand with the contouring of the facets making it lie in your grip as if it were made for it. I found the Operator’s slender yet robust build allows it to tackle heavy cutting chores without the unnecessary bulk. It also carries well in the pocket or on the belt.

Stroup Knives HM1
The HM1 from Stroup Knives showcases a prominent clip point blade and a sweeping cutting edge. Both help it excel in either defensive or conventional chores. As a bonus, the tip of the blade is so acute it tackles precise cutting chores with ease.
Based in Fayetteville, North Carolina, Stroup Knives specializes in tactical and utility fixed blades. Company founder Chris Stroup is an Army veteran with 11 years of service to our country. His final assignment was with a special missions unit based out of Fort Bragg. Medically discharged in 2020, Stroup Knives was born, and in 2022, Stroup made the decision to go full-time into knifemaking.
Stroup Knives’ latest knife, the HM1, represents a multi-use fixed blade for utility, tactical and outdoor use. The design’s focus is on retention, control and high utility. The blade of the HM1 is 4 inches in length and made of 1095 carbon steel with a black stonewashed finish. The clip-point shape gives the blade its distinct bowie-like profile. Honestly, the tip on this one is flat-out wicked! It’s pointy and will penetrate softer materials easily.
The knife sports a distinct machined texturing, making it easily recognizable as a Stroup; a lot of the company’s knives have this distinguishing pattern. Proportional to the blade, the handle also measures 4 inches and has several features making the HM1 noteworthy. Most prominent is the finger ring. The ring provides a measure of security and retention by allowing you to lock your grip in place through it with your pinky finger. Further, the feature makes dropping the knife, even by accident, difficult.
Stroup uses G-10 for the handle, and it sports a 3D-sculpted pattern to aid hand traction. Each HM1 comes with a fold-over Kydex sheath with Teklok attachment. The setup is Spartan, but hey, this style of sheath is widely used in the industry and it always works well. It locks the knife in place and there isn’t any rattling. The belt attachment is solid and is easy to put on and take off without removing your belt.
Made from 1095 carbon steel, the HM1’s blade is simple to maintain and take a wicked edge. Double-walled cardboard melted like butter under the knife’s edge.
The HM1 can function as both a backup weapon and a utility tool. The blade profile is not only excellent at puncturing, but also is fine enough at the tip for precise cutting or scoring tasks. The knife’s 1095 carbon steel is widely praised—it sharpens quickly and it is less expensive than all of the high-performance CPM stainless steels.
I appreciate the dual role the HM1 plays. The knife seems well thought out as an edged weapon and an EDC tool. The HM1 is available in two black acid wash blade finishes (one with black G-10 handles, the other with OD green G-10 handles) and two Cerakote blades (FDE and OD green G-10 and black with black G-10 handles).

Spartan Blades Spartan Harsey Dagger
The Spartan Harsey Dagger’s handle has a lot going on with a distinctive oval profile that lies in the palm naturally and makes the edge easy to index—even in low-light environments.
Spartan Blades, founded by retired Green Berets Curtis Iovito and Mark Carey, has earned a strong reputation for high-end factory-made tactical fixed blades. Several of those knives were designed in collaboration with Bill Harsey, a well-known knifemaker who specializes in custom tactical fixed blades that are on the next level. Harsey’s impressive background includes knife work for the late legendary Col. Rex Applegate, prototyping the Applegate-Fairbairn fighting knife.
The Spartan Harsey Dagger takes what Harsey learned from working with Col. Applegate and applies it to modern-day production tactical fixed blades. It is a modernized version of the Fairbairn-Sykes, if you will. It has an upgraded handle design, upgraded materials and a beefier build overall, yet still retains the design hallmarks of the legendary F-S.
The dagger has a 6-inch-long double-edge blade, hollow ground from premium CPM MagnaCut steel. A black DLC coating is applied for low reflectivity, as well as boosting the corrosion-resistant properties of MagnaCut. The knife also has some notable features like a long, tapered flat section in the middle of the blade for lateral strength and the hollow ground bevels, thinning the edge for a sharper blade.
The handle is where the magic begins and what sets the Spartan Harsey Dagger apart from the rest. The finger recesses behind the guard help to index your grip and lock it in your hand. The recesses have traction notches in them, not only for a non-slip grip but also for tactile cutting edge orientation. The way the handle flares out toward the butt of the handle catches your pinky to prevent rearward sliding and aids in references a clean grip to clear the blade from its sheath. The Spartan Harsey Dagger has a hidden tang design with the Micarta scales fully encapsulating it. There is a bit exposed at the very end of the handle for use as a non-lethal striker. The double hand guard is angled away from the user a bit to provide a comfortable thumb rest.
The Spartan dagger is made from thicker stock, even so, the hollow-ground bevels and a needle point, the knife punches cleanly and quickly.
Each Spartan Harsey Dagger comes with a Kydex carry sheath with MOLLE-compatible straps. The sheath locks on the double guard and provides a very secure fit with zero rattle or any other movement.
Keep in mind a knife like the Harsey Dagger is not a box cutter or a utility knife. If you need a working knife, look elsewhere. It is likely best served, away from the military, as a backup weapon to a firearm. The blade is engineered to penetrate and it’s frightening how adept it is at its job.
One thing most folks agree upon, the Harsey oozes sexiness, with its curvaceous handle and no-nonsense blade. It is a looker for sure, but it can also perform when called upon. The Spartan Harsey Dagger comes in two colors—the black blade and black Micarta handle, as evaluated here, along with an FDE blade and black Micarta handle.
The points at the ends of the CRKT Xolotl OTF handle not only add visual style but also allow the knife to be used as a non-lethal defense striking tool when the blade is retracted into the handle.
The Xolotl (Show-low-tol) Automatic is CRKT’s second OTF auto in the company’s lineup. The double-action was designed by Michael Rodriguez, a former Green Beret and veteran. It is named for the Aztec god of lightning and fire.
The overall look of the Xolotl Automatic is symmetrical in both handle and blade shape. In turn, it is very pleasing to the eye. The blade is 3.5 inches and is a true dagger, sharpened on both sides. CRKT’s steel of choice is CPM MagnaCut—pretty much the perfect high-end blade material, if there ever was one.
The handle is machined from T6 6061 aluminum alloy, and its thickness is kept to a minimum so that the Xolotl carries well in the pocket. It also features circular machined grooves for enhanced grip retention. Interestingly, there are 21 grooves, one for each year of Rodriguez’s service. The handle ends up tapering to stylized points of sorts, adding intrigue to the overall look by possibly providing a non-lethal method of striking defense. A deep carry pocket clip rounds out the entire package, allowing the Xolotl to ride undercover. A sliding switch on the handle spine controls the blade’s movement, which is very swift and secure.
The thinner blade stock on the CRKT Xolotl OTF allows for great penetration. Additionally, its MagnaCut steel holds an edge like nobody’s business and is highly corrosion resistant.
Dagger blade OTF’s are very cool-looking, and they are fun to own. But they are limited in providing a full functional cutting tool. By this, I mean that given the material removed to form a dagger profile, it is more susceptible to damage by torque. Further, dual edges mean you can’t use a digit to exert more latitudinal force in a cut or more control. Yet, the dagger does have the advantage of two cutting edges, so if you damage one, you have the other.
All this being said, the Xolotl is a capable cutter, opening mail, packages, cutting up cardboard boxes and anything else that you need to slice. I would not subject the knife to hard use of any kind, given its thinner blade.
Böker teams up with popular German bushcrafters to deliver a pocket-friendly, G10-scaled multi-tool packed with essential field implements.
The multi-tool market has long been divided between heavy-duty plier platforms and traditional red-scaled pocketknives. Böker bridges that gap with the Naturensöhne MK II NXT, a fresh take on the classic multi-functional folder built specifically for outdoor utility.
Created in collaboration with Die Naturensöhne, the popular German YouTube duo known for their bushcraft challenges, this tool ditches shiny plastic for field-ready ergonomics. The handles feature textured forest-green G10 scales that offer a solid, slip-resistant grip when working in wet conditions.
At the core of the tool is a 2.8-inch drop-point blade made from Sandvik 12C27 stainless steel. Finished in a muted grey stonewash, the blade relies on a traditional nail nick and non-locking slipjoint mechanism. That two-handed opening makes it a legal-friendly option in regions with strict lock-knife regulations.
Instead of clogging the frame with rarely used gimmicks, Böker packed in targeted outdoor implements:
A wood saw for clearing branches or notch-cutting
Mini combination pliers for light bending tasks and quick repairs
A reamer and awl for punching leather, wood, or gear
Fine tweezers and a scale-mounted toothpick
A dedicated glass breaker located at the pommel
Weighing in at 4.23 ounces and measuring 6.57 inches overall, the MK II NXT carries like a standard pocketknife thanks to an integrated tip-down pocket clip. For campers, bushcrafters, and daily carry enthusiasts looking for multi-tool versatility without the bulk of a full plier chassis, Böker’s latest collaboration delivers a slick, highly functional compromise.
