Twitch II features a pass-through lockbar (patent pending) from which the "kick" of the blade sticks through. By pressing on the "kick", one is able to initiate the opening of the blade. S.A.T. SOG Assisted Technology then takes over to finish opening and to securely lock the blade open. Now available with a rosewood handle for that classic outdoorsman look.
