Relentless Fillet Knife takes an entirely different approach, focusing on how the blade wears instead of the wear rate. Relentless’ patented Perpetual Edge Technology was inspired by nature’s solution to preventing edge wear. It replicates the self-sharpening teeth of the beaver, which has a relatively soft “dentin” backside and a tough, iron-fortified enamel on the front. George Lambert who owns Relentless goes in depth about the technology that makes these knives so unique with The Fisherman’s Matt Broderick.
