Medal of Excellence Awarded to
Relentless Knives by 10th Mtn Div. U.S. Army, Camp Liberty, Iraq 2006

Knife from PUNISHER WAR ZONE 2008
RELENTLESS KNIVES  are made with the military in mind, offering  you a knife that is as flexible and durable as possible in a variety of ways.   We  want to make sure that the RELENTLESS knives exceed the needs of professional soldiers, policemen and adventurers.
Why?    We are Committed to Excellence! You won't find Relentless Knives everywhere, in fact, production is all by hand, and .......well,  it's a slow process to say the least.
But, well worth the time, as they are made to last a lifetime,
and endure the rigors of battle.
 I use  materials and  processes that are expressly intended to resist the rigors of extreme abuse, and,  have  invested lots  in testing the products myself, and then having them tested further by objective individuals in a sincere effort to bring you a product that is strong and reliable.
In todays world, this is rare.
Relentless Knives are made one at a time by hand.
With no options, each Relentless Knife is Zone Tempered, a process used by Japanese Samurai sword makers for thousands of years, which 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 resharpen easily.
The Zone tempered knife is super strong, and will handle the most extreme conditions with ease.
But..... for the most demanding of customers
futher enhancements are available which include hand forging,  tripple thermo
cycled, quenched then Cryogenic treatment, followed by tripple tempering.
Our goal ...... extreme functional reliability.
that propels many to excellence is built into each of my knives. You'll feel it as you hold the knife, and it will be with you, so long as you own your
