About Us

Introducing Relentless Knives: where innovation meets craftsmanship. Our fillet knives feature Perpetual Edge Technology for unmatched sharpness and durability. Designed for anglers, chefs, and outdoor enthusiasts, our knives promise precision with every cut.

Relentless Knives feature patented Perpetual Edge Technology inspired by the self sharpening teeth of the beaver.

A beaver’s teeth have a soft back side and a hard, iron-fortified front side that creates a differential in hardness and different wear rates between the two sides. As a result, one side wears faster and along the other. A Relentless Knife creates the same differential in hardness and different wear rate between the two sides of the blade by adding a hard carbide/crushed diamond “Power Strip” fused along one side of the blade edge for a perpetual, lifelong edge that sharpens as it cuts.
