SOG Knives Flash I Knife - $54.35

Barring fully-automatic knives (which are illegal for civilian use), there's no faster blade deployment mechanism on the market than the S.A.T. system in the SOG Flash I. A short movement of the thumb stud starts the show, then BANG! The S.A.T. (SOG Assisted Technology) coil spring takes over, whipping the blade fully open and locking it in place with a sliding piston. The Flash I's cryogenically-treated, titanium-nitride-coated AUS-8 steel blade takes a keen edge, and the textured, anodized aluminum handle scales are made to withstand years of hard use. SOG's reversible pocket clip allows you to carry this knife discreetly without sacrificing easy access. - $54.35
