Welcome to our 2019 Catalog
~

Each Relentless knife is handmade by Daniel M. Certo from Top Quality raw materials especially selected  and prepared to endure a lifetime of hard and heavy use at reasonable prices
All Relentless knives are
ZONE tempered for incredible strength.
Zone Tempering, a process used by Japanese Samurai sword makers for thousands of years, results in a super strong blade, with spring temper in the spine and 58rc hardness on the cutting edge, This gives you a knife that resists breakage even with the application of great lateral
forces, that will hold an edge well, and re sharpen easily. 
Then add  my
trademarked tri asymetrical grind which further enhances resistance to lateral force and results in a knife more than a cut above
the rest

Should you find yourself in a burning building, vehicle, or air craft your knife may need to perform as a pry bar, rope anchor, glass breaker or saw. 
Join Individual Soldiers, Police, Search and Rescue Team members, as well as Campers, Hikers Backpackers, Hunters, Farmers and Outdoor Adventurers through out the world who own and keep close a Relentless Knife because they understand that desperate situations happen and this one simple multi use tool can save their lives.
