Comparing Smith’s Flex Fillet and Bear & Son Smooth White Bone Pro Fillet in fish-skinning dominance.

I was just about to type “fishing season is nearly upon us.” Living in Canada, it has never stopped. Up here, thousands of fishermen are manning their shanties, huddled over a hole, heaters blazing their favorite brand of barley pop nearby. Up north, fishing is a sport that runs year-round.

Why do men go ice fishing? Maybe they go for the love of it? Maybe the solitude and peace on the ice? Either way, they are out there. And certainly, a part of their kit is a good fillet knife. If you intend on eating some of what you catch, you need one. Which brings us to our topic.

We’ll head-to-head two fillet knives at opposite ends of the price spectrum. At the budget end is the Smith’s Flex Fillet Knife, and in the premium tier, the Bear & Son Smooth White Bone Professional Fillet Knife. Both knives have 7-inch-long blades, and both will be tested on some fresh catch from Lake Erie. Crossing my fingers, we get fillets for a meal.

A buddy of mine who is braver than I for facing the cold brought in a variety of pickerel (walleye for my American readers) and my favorite, yellow perch. Anyway, let’s talk knives. Some would figure that putting a $145 dollar knife up against a $20 isn’t a fair comparison. I would suggest that price sometimes doesn’t matter as much as value.

Tale Of The Tape

Handle ergonomics is important in a knife used for long periods of time. It is one thing to chop an onion and a completely different thing when you need to manipulate a blade to make detailed cuts repeatedly. Ergonomics on the Bear & Son are pretty good. The overall profile of the handle has the right contours. Out of the two, there is no doubt that the White Bone Professional has better looks with its split 25 percent black and 75 percent white handle scales. Part of the presentation of the handle is black liners that run into the black bolsters. Bear & Son use screws to fasten the scales to the full tang design. They also include a lanyard hole.

Smith’s, on the other hand, goes with a light injection-molded plastic handle. Unfortunately, they do not detail what material the handle is made from, and since do not play guessing games I will not hazard a misinformed guess. The molded handle on the Smith’s is lightweight. On the weight (without sheaths), the Bear & Son weighed in at 5.46 ounces, and the Smith’s weighed in at 2.98 ounces, according to my kitchen scale. Therefore, the Smith’s came in at almost half the heft. If you prefer a knife with a little heft to it, the Bear & Son is your model.

Sheaths for these knives are not a main area of concern, as a fillet knife isn’t generally meant for belt carry. You do want the blade protected. Naturally, you want to avoid holes in whatever you choose to tote your fishing gear in. Smith’s comes in a very minimal sheath, no belt loop and plenty of drainage holes, allowing the blade to dry. All those slots make sure the sheath is easy to wash out. The Professional comes with a sturdy molded sheath with various lashing points so you can attach it to your gear. Furthermore, it has a great friction lock-up. The only drawback to the Bear & Son sheath is a tiny drainage hole. This, however, is easily fixed with a large drill bit.

Fillet Fray

The Professional is made from 14C28N stainless steel, popular in fishing and fillet knives. The Smith’s is listed as a 400 series stainless steel, found in more budget-conscious blades—particularly kitchen cutlery. Despite the differences in materials, the Smith’s knife was sharp out of the box. The blade cleaned the fish with ease. We cut around the ribs to start, and, for the test, we cut through the ribs. Then, we deboned the fillets.

Next came the White Smooth Bone Professional. Right off, it needed work on its edge. Luckily, my friend had a draw-through type sharpener, and he touched up the edge. This improved the knife’s performance a bit, but it was still not optimal for the job at hand. Cutting through the ribs was more like breaking through them. Out-of-the-box sharpness, hands down, goes to the Smith’s Flex. In fact, we finished the rest of the haul with the knife, and it is still sharp enough to clean fish.

I will note that I worked on the Professional later after the test and did get the edge up to snuff, but it wasn’t there fresh from the box.

Final Cut

My final thoughts on the two are, for the money, the Smith’s probably gives a fisherman as much knife as most he’ll need. And it does so from the get-go. How will it perform long-term? I will have to do the hard work of going fishing to find out.

As for the Bear & Son? If you like the knife, you likely have to do some work to get its performance up. Please keep in mind that these are samples of one of each knife and may not hold true as a rule for either blade across the board. In the knifemaking process, the final step of putting an edge on the blade is mostly still done by hand. Whoever put the edge on the White Smooth Bone didn’t form it properly. Human error isn’t uncommon.

Either choice, good luck out there, and catch a bunch.
