Looking at the intricate construction of the Twitches reminds us of the workings in a fine chronograph watch...everything right and precisely in its place. These techno wizards feature a pass-through lockbar from which the "kick" of the blade sticks through. By pressing on the "kick", one is able to initiate the opening of the blade. SOG Assisted Technology then takes over to finish opening and to securely lock the blade open. What makes these space-age little gems even more beautiful is that they are also affordable!
