The Trench Raider series is definitely something new and exciting. It combines two popular favorites- knives & knuckles - into a WWII styled trench knife! The handle of the Trench Raider has red coated aluminum inserts that sit on top of a black steel lines. The bottom liner extends out into nicely contour knuckle guards which protect but are sturdy enough to use on the offensive as well. The tanto point blade is coated 440 stainless steel. The blade opens with a push of the spine flipper (the knife is spring assisted). The trench raider also has a removable steel pocket clip (tip up). Despite the impressive armament the Trench Raider is still relatively thin at only 5/8" thick.
