A member of Robert Young Pelton's arsenal of Hostile Environment Survival Tools, the HEST/F Shred folding knife - like all of the DPx Gear knives - was designed to be used in the most brutal of circumstances. The blade is made from Niolox steel and at only 2.26" this knife is very pocket friendly. If you want to adjust the pivot screw or remove the attached clip, you need only a 7/64" hex driver. And there's a Tungsten carbide glass breaker at the base of the handle if the need arises. If not, there's a bottle opener to help you celebrate.
