The Flash family of knives feature SOG Assisted Technology (S.A.T.), which employs a powerful piston lock that is easily released with a sliding button. The Flash II Tanto (Straight edge) comes with glass-reinforced nylon (GRN) handle and straight edge, Satin finished blade. All Flash knives come standard with SOG's patent pending, reversible bayonet mounted clip that ensures the lowest, most discreet carry possible.
