Each 4034 stainless steel blade is teflon-coated and features the ultra-fast M.A.G.I.C. assisted-open mechanism which can be activated by the ambidextrous thumb stud or the finger actuator on the back of the blade. Once activated the blade springs open at a phenomenal speed. A blade safety switch ensures no accidental opens and a liner lock ensures the blade doesn't accidentally close while in use. 3.4 in. blade, 7.7 in. overall, 4 3/10 in. closed.
