Spring Assist - S&W Black Operations - Spear Point w/ Plain Edge
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.
How are Spring Assist different from a Gravity Knife or Switchblade Knife?
Gravity or Switch Blade knives feature a button, level, or other type of switch that releases a spring pressure to automatically open the blade. On a Spring Assist knife, there is no separate button or switch. Instead, you apply pressure to part of the blade to begin the opening process. This is usually a small bump of metal which sticks out under the knife, making it fast and comfortable to use. Once you press on that part of the blade, it automatically opens and locks into place. Since the action of opening the knife is started by pressing the blade metal, instead of a button or switch, it is considered to bypass the laws which ban Switch Blade knives.
