The Flash II 3.5″ Knife has got to be one of the coolest knives weÂ’ve ever seen. Forget its wicked-quick blade access, that it handles like a race car on rails, or that it locks up like Alcatraz. It just looks and feels extraordinary. 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 I (1/2 serrated) comes with Glass-reinforced Nylon handle and 1/2 serrated, black TiNi coated blade. All Flash knives come standard with SOGÂ’s patent pending, reversible bayonet mounted clip that ensures the lowest, most discreet carry possible. We also had the foresight to incorporate an additional safety lock that gives added security when the blade is closed. Note that when the safety shows red… YOU ARE READY TO GO!
