Why Relentless?

Perpetual Edge Technology

For centuries, knife makers have tried to solve the problem of "edge dulling" by focusing on improving the rate of wear by making the blade harder so it wears more slowly and stays sharp longer. The problems with this approach are the harder the knife the more brittle the edge, the more difficult it is to sharpen, and it still needs to be resharpened after filleting a couple of fish. Our Perpetual Edge technology is engineered to control the way the edge wears rather which makes it to wear to a fine and sharp edge as you cut and rarely requires any edge maintenance. If you eventually feel you want to maintain or sharpen our knife that process is nothing like sharpening a conventional knife, does less damage and is so simple.

“NeverRust” Titanium Blade

Relentless™ Knives feature a 100% aerospace grade titanium blade. Titanium is extremely lightweight, which means less wrist fatigue while filleting, and extraordinarily strong. But, most important, titanium is corrosion proof. In other words, a Relentless™ Knife will never rust. This is an ideal attribute for a fillet knife, especially for the saltwater angler.

"True Grit" Glass-Reinforced Handle

Invariably, the first thing people notice on a Relentless™ Fillet Knife is the extreme grippiness of the True Grit handle. The handle is made of a glass reinforced ABS plastic but covered with the same gritty material used to create the non-slip, non-abrasive surface found adjacent to swimming pools. This ensures you won’t lose your grip while filleting even if you have wet or slimy hands.

"MeatCutter" Micro-Serrated Cutting Edge

The carbide and diamond composite cutting edge on a Relentless™ Knife have micro-serrates meaning it has tiny jagged, saw-like protrusions that function like thousands of micro-blades that further enhance the ability of the knife to cut soft, pliable things like fish which otherwise squish (like a tomato).

“SlickCut” Anti-Friction Treatment

One side of every Relentless™ Fillet Knife is treated with SlickCut, an anti-friction boron nitride compound which enhances the lubricity of the cutting edge to reduce friction and improve cutting performance.
