Twitch II The Twitch is the next evolution of the classic lockback design, with its patented pass-through lockbar from which the kick of the blade sticks through. Thanks to S.A.T.(SOG Assisted Technology), the blade is propelled open once the operator has initiated opening using the kick . Invented by Spencer Frazer, the Twitch is a 21st century lockback.

The money/pocket clip can be used for low-carry or securing dollar bills and cards. Also included is a small safety that helps insure the knife won't open until you're ready. The safety can be engaged once the blade is open so that the locking bar cannot be released. So, in essence, you have two locks.
