The Flash line of folding knives debuted SOG’s patented 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 its fast start and power curve throughout the movement of the blade. The reversible low-profile clip can be used in either left or right side pockets for low-carry. Also included is a small safety that helps insure the knife won’t open until you’re ready.
