The K.I.S.S. in the Dark features blade, frame, clip and hardware in black non-reflective plating that is tough and long lasting. Like all folding knives in the K.I.S.S. family, Ed Halligan's unique two-piece construction features an integral frame lock, and a breakthrough design which seals the cutting edge against the handle. A thumb stud is used to one-hand open the blade, and as the blade is fully rotated open, the frame lock snaps crisply in behind the blade to give a sound lockup. The blade can be closed with one hand, simply by releasing the frame lock. The Original K.I.S.S. blade shape is Tanto-inspired Chisel-Point grind on the front and flat on the backside so that when the blade is closed onto its handle/frame, the precision fit effectively seals the cutting edge to the frame, even though it's exposed. Both Razor-Sharp and Combined Razor-Sharp and Triple-Point Serrated edge grinds are available. Both blade and frame are 420J2 stainless.
