With its first foray into knifemaking, Work Sharp cooks up a doozie–a knife that’s both a folder and an automatic.

Work Sharp has five decades of experience keeping the knife world as sharp as ever. At that time, the tool and knife sharpening implements company had never dipped its toe into knifemaking—until now.

At the 2025 BLADE Show, the Ashland, Ore., company will debut its first foray into edged tools with the introduction of the RMX EDC-style knife. And while the pocket partner might seem like just another folder at first blush, the knife’s internals make it an innovative addition to nearly anyone’s collection. Work Sharp isn’t lying when it says the RMX is “Your knife. Your Way.”

Manual Or Auto

The groundbreaking aspect of the RMX (Replaceable Mechanism Exchange) is that the knife is both an auto and a manual action. And no, it’s not just manual by muscling open an auto or flicking open a manual.

As its name suggests, the RMX utilizes what Work Sharp claims is the first-ever interchangeable pivot cartridge. Essentially, the knife comes with two pivots—one ball bearing (manual) and one spring-loaded (auto). Simply switch one out for the other via a 2mm hex head.

Furthermore, internally, the tension is adjustable thus, the deployment of the blade in both manual and auto configurations is tunable. It’s a slick system, not only because of the implications of having two knives in one, but also legally.

Theoretically, the RMX should make shipping the sometimes automatic knife all the simpler, while also giving users more control over exactly what they’re carrying. Not to mention, it’s a plain and simple concept.

As for deployment, a push-button near the pivot kicks the blade out as an auto and acts as the release as well.

RMX Blades

The Work Sharp RMX comes in two blade styles and three sizes. The one I’ve seen making the most headlines is the full-sized 3.2-inch Reverse Tanto profile—a wicked-looking blade with an ultra-thin edge and excellent slicing properties. The company is also offering a drop-point profile in two sizes, 3.2 inches and a compact 2.4-inch option. Both come with a saber grind.

As for blade material, Work Sharp utilized Crucible Industries’ CPM 3V steel. This is a solid choice, given the metal is known for its toughness, high wear resistance and ability to hold a very fine edge.

RMX Handle

Interestingly, especially for a knife with auto guts, the RMX is feather light, thanks mainly to its handle. Work Sharp opted for magnesium, keeping the knife between 2.24 ounces and 2.7 ounces, depending on its configuration. Additionally, the material imparts a good deal of stiffness to the knives and, with a gray Cerakote treatment, proves plenty durable, not to mention eye-catching.

Complete Package

Even for the sheer novelty, the Work Sharp RMX is an intriguing system made even more so due to an affordable price.  The RMX compact has an MSRP of $130 and the full-sized version an MSRP of $140, making the line competitive in both the folder and auto markets—very competitive. Overall, the offering makes one wonder why it took Work Sharp so long to take a stab at knife manufacturing.
