The Heckler and Koch Scorch Code 3 knife features a very cool double action mechanism. The secret: to fire the knife, slide the top scale away from the blade and POW! The Scorch knife can also be opened manually via the dual thumb studs. The blade is D2 tool steel with a reverse tanto design with a black finish and partially serrated edge. The handle is textured G10 with a liner locking frame. Also includes tip-down pocket clip.
