Relentless Knives in HOLLYWOOD

Proud to say the Relentless M4X  was chosen out of 30 knives
to be the Official knife of  the Punisher
and appeared in the 2008 Lions gate
movie  "Punisher War Zone"
The first 5 minutes of the film
deticated to the knife.

All of my Relentless models are Zone Tempered, a process used by Japanese Samurai sword makers for thousands of years, results in a super strong blade, with spring temper in the core 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. You get, superior strength and durability and heavy last ditch personal protection in a handy all around utility knife that you will love.
