The Flash line of folders debuted SOG's patent pending S.A.T. (SOG Assisted Technology). This mechanism helps propel the blade open once the operator has initiated the one-handed opening action. They're as fast as lightning, safe, and provide an extremely strong blade lock. This opening action is uniquely different from all others with a fast start and a power curve throughout the movement of the blade. When closing the blade into the handle you actually feel as if you are cocking a side arm as the blade is held securely inside the handle.

S.A.T. is the framework for this line of lightweight folders. The bolt action lock is easily released with a sliding button. SOG also had the foresight to incorporate an additional safety lock that gives added security when the blade is closed. Note that when the switch shows red, you are ready to go.

In addition to S.A.T., the handles of the Flash are molded from glass reinforced Zytel and are contoured with a new ergonomic sensibility that makes the knife a pleasure to use. SOG has also incorporated a new ambidextrous clip device that is easily interchanged. This bayonet-mounted clip extends from the end of the hand for the lowest discreet carry possible.
