The Twitch XL from SOG features a pass-through lock bar 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 (S.A.T.) then takes over to complete the full opening and solid lock-up of the knife.The S.A.T. mechanism only propels the blade open once the operator has initiated the one-handed opening action. The locking safety, which iinsures the blade doesn't open until the user is ready, can be engaged once the blade is open so that the locking bar cannot be released, in essence creating a double lock. The Twitch XL is constructed with a hard-anodized machined aluminum handle and stainless-steel blade.
