The Heckler and Koch Scorch 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 thumbstuds. The blade is N680 steel with a reverse tanto design with a black finish and partially serrated edge. The nylon handle is compression molded glass filled nylon with a liner locking frame. Also includes tip-down pocket clip.
