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 as hard as possible so it wears more slowly and stays sharp as long as possible. The problem with this approach is that the blade edge will become dull and the harder the blade, the harder it is to sharpen, and the more brittle the edge.

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 extremely resistant to corrosion and degradation. In other words, a Relentless Knife will never rust. This is an ideal attribute for a fillet knife, especially for the saltwater angler.

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.

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 but covered with the same gritty material used to create the non-slip surface found adjacent to swimming pools. This ensures you wont lose your grip while filleting even if you have wet or slimy hands. The black True Grit surface is also faceted meaning it scatters light in every direction which means it is non-reflective and will never get hot, even if left in the hot sun.
