This model is one of the first of Kershaw's Ken Onion SpeedSafe knives and still among the best. Features 13C26 stainless-steel blades for strength and corrosion resistance. The Blackout's blade is also coated with scratch-resistant Tungsten DLC for a handsome, non-reflective surface. Contoured handle made of injection-molded polyimide, an extremely durable engineering plastic, for a comfortable and stable grip. Stainless-steel liners add to the overall handle strength.
