The introduction of the new Flash line of folding knives debuts SOG’s new 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 fast as lightning, safe, and provide an extremely strong blade lock. This opening action is uniquely different from all others with its fast start and 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.
