The Trench Raider US 1918 Style Spring Assisted Knife from Tiger USA is definitely something new and exciting. It combines two popular favorites- knives & knuckles - into a WWI styled trench knife! The handle of the Trench Raider features black coated aluminum inserts that sit on top of steel lines. The bottom liner extends out into nicely contoured knuckle guards which protect but are sturdy enough to use on the offensive as well. The drop point blade is bead blasted 440 stainless steel (partially serrated). 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.
