In 1980, Pete Gerber introduced the L.S.T., the first pocket knife to use an all synthetic handle, revolutionizing the way the world thought about knives. The Gerber L.S.T. knife combines lightweight, smooth action and tough construction. The Gerber LST blade is made of durable surgical stainless steel. Checkered fiberglass-filled nylon handles ensure strength, durability and a non-slip grip. A Blackie Collins original design.
