The SOG Flash I with a Aluminum handle and black TiNi blade features SOG Assisted Technology (S.A.T.), which will give you wicked-quick access to your blade, and S.A.T. is a powerful piston lock that is easily released with just the push of a sliding button. Equipped with a black TiNi coated ½ serrated blade and a hard-anodized 6061-T6 aluminum handle, the Flash I is built to last. A reversible bayonet mounted clip ensures the lowest, most discreet carry that is possible. A additional safety lock gives you added security when the blade is closed. The SOG Flash I takes the cake for a knife that feels and looks extraordinary.
