Relentless' patented Perpetual Edge Technology was inspired by nature’s solution to preventing edge wear, replicating the self-sharpening teeth of a beaver. The beaver's teeth have a relatively soft “dentin” backside and a really hard, iron-fortified enamel on the front. This creates a differential in hardness between the front and back, allowing the softer dentin back to wear more quickly relative to the harder iron-fortified front edge, leaving a thin, razor-sharp edge. This results in a perpetual, lifelong edge that sharpens as it cuts. SETTING THE STANDARD FOR 15 YEARS! Fifteen years of blood, sweat, and hard work have led to the company you see today! Originally founded as Titan Knife Technologies in 2009, we have been crafting the best knives on the planet and developing new technology that will take knives into the future. We re-branded to Relentless Knives in 2023 and haven’t looked back since. We wanted an identity that resonated with our brand-new Perpetual Edge Technology. We’re excited to see the future of this brand as we continue to relentlessly innovate! VETERAN OWNED \u0026 OPERATED Relentless Knives is American owned and operated! With a commitment to quality and a desire to craft a knife that lasts a lifetime, we thought it was only right to keep it local.

Relentless' patented Perpetual Edge Technology was inspired by nature’s solution to preventing edge wear, replicating the self-sharpening teeth of a beaver. The beaver's teeth have a relatively soft “dentin” backside and a really hard, iron-fortified enamel on the front. This creates a differential in hardness between the front and back, allowing the softer dentin back to wear more quickly relative to the harder iron-fortified front edge, leaving a thin, razor-sharp edge. This results in a perpetual, lifelong edge that sharpens as it cuts. SETTING THE STANDARD FOR 15 YEARS! Fifteen years of blood, sweat, and hard work have led to the company you see today! Originally founded as Titan Knife Technologies in 2009, we have been crafting the best knives on the planet and developing new technology that will take knives into the future. We re-branded to Relentless Knives in 2023 and haven’t looked back since. We wanted an identity that resonated with our brand-new Perpetual Edge Technology. We’re excited to see the future of this brand as we continue to relentlessly innovate! VETERAN OWNED \u0026 OPERATED Relentless Knives is American owned and operated! With a commitment to quality and a desire to craft a knife that lasts a lifetime, we thought it was only right to keep it local.

beaver, which have a relatively soft “dentin” back side and a hard, iron-fortified enamel on the front. This creates a differential in hardness between the front and the back in which the softer dentin back wears more quickly than and along the harder, iron-fortified front side creating a perpetual, lifelong edge that sharpens as it cuts.\u003c\/p\u003e\u003cimg src=\\\"https:\/\/m.media-amazon.com\/images\/S\/aplus-media-library-service-media\/937c4dbd-4be8-4d36-aadb-afc9d76ca944.__CR0,0,970,600_PT0_SX970_V1___.png\\\" class=\\\"aplus-img\\\" style=\\\"max-width:100%;height:auto;display:block;margin:0!important;padding:0!important;border:0;vertical-align:top;line-height:0;font-size:0;\\\" loading=\\\"lazy\\\" \/\u003e\u003ch5\u003eRELENTLESS KNIVES FEATURE PATENTED PERPETUAL EDGE TECHNOLOGY INSPIRED BY THE SELF SHARPENING TEETH OF THE BEAVER.\u003c\/h5\u003e\u003cp\u003eA 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.
