C90B-A Push Button Lock Auto Plain Edge Folding Knife Stay protected, secured and ready for action while carrying the Push Button Lock Auto Plain Edge Folding Knife from Schrade. Boasting one of the quickest deployment actions on the market, the knife features a precision constructed push button release for effortless one-handed use. Once opened, the knife's AUS-8 steel blade offers a razor sharp cutting edge that is not easily dulled. The higher carbon content of the steel used creates a harder exterior that does not chip when put up against hard tasks. An ergonomically shaped handle is designed to match the natural curves of the palm to deliver a secure grip with smooth handling. ts black handle is made from aluminum with a mixture of textured and coarse surfaces for a secure grip. A safety lock prevents the knife from accidentally opening while a glass breaker at the butt offers additional functionality. It comes with a reversible pocket clip.
