Kershaw's SpeedSafe® assisted opening system is one of the most recognized and trusted knife technologies in the world. Developed with legendary designer Ken Onion, SpeedSafe® uses a precision torsion bar mechanism built into the handle to deliver a blade deployment that is fast, smooth, and completely one-handed. The moment you apply light pressure to the thumbstud or flipper tab, the torsion bar snaps the blade to full open — making SpeedSafe® knives a go-to choice for everyday carry enthusiasts, outdoorsmen, and working professionals alike. Unlike automatic knives, SpeedSafe® requires deliberate user initiation, keeping it legal in the vast majority of U.S. states.
Kershaw offers SpeedSafe® assisted opening knives across an enormous range of styles, sizes, and price points. Handle materials span glass-filled nylon and aluminum to G-10 and premium stainless steel, while blade steels range from dependable 8Cr13MoV all the way up to D2, 14C28N, and CPM 20CV. Every knife ships sharp from the factory, locks up solid with a liner lock or frame lock, and is built to deliver the same crisp, reliable action thousands of cycles down the road.
