The Blackout 1550ST is another great Ken Onion designed knife from Kershaw! It features a Sandvik 14C28N stainless steel blade with a Tungsten DLC black finish and a partially serrated edge. The SpeedSafe assisted opening mechanism quickly deploys the blade with a push of the thumb stud and lockup on the Blackout is solid via the steel liner lock. The glass-filled nylon (GFN) handle is lightweight and textured for positive grip and performance with a nested steel frame for strength. The removable tip-down pocket clip is comfortable for everyday carry.
