Implement with SOG Assisted Technology (S.A.T.), the Twitch is extremely quick to open with either hand using the double thumb studs or kick on the back. Its full metal construction is durable and sturdy. The clip can be used for low-carry or securing dollar bills and cards. Incorporated into the design is versatile safety lock that helps insure the blade will not open while being carried or close unexpectedly while in use. The SOG Twitch series is a great EDC with a variety of options to choose from. *Rarity note: This “checkered” model is the most rare Twitch II. More rare than the prevalent Black Tie or other types. Production was limited to 750, but were made to order. Also, the SOG warehouse sale in April of 2022 uncovered at least a hundred unused graphite checkered bodies that would indicate far less than 750 were ever purchased.
