Flash I and II - The Flash line of folders debuted 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 are as fast as lightning, safe, and provide an extremely strong blade lock. Mini X-Ray Vision - The SOG Mini X-Ray features the same award-winning, ATS-34 steel blade as the original SOG X-Ray Vision, but is almost an inch shorter. Pentagon Elite - The Pentagon Elite was created to fulfill the many requests for a folding version of the original SOG Pentagon and Mini Pentagon fixed blades. A major tactical advantage of the Elite is the incorporation of SOG's new Arc-Lock. SOG Trident - Sea, Air and Land. SOG's mission was to create an updated SOG folding knife based on historical proven design but launched from a platform of new technology. Somehow, when you see it, you immediately know it is a SOG.
