The SOG-TAC is SOG's first automatic knife. The SOG-TAC is remarkably lightweight and thin so you won't feel like you're hauling a lead weight. The AUS-8 stainless steel Tanto blade is black TiNi finished with a partially serrated edge. The action is quick and the lock-up is flawless. The hard anodized handle is machined 6061-T6 aluminum with comfortable finger grooves and a safety to lock the blade open and closed. The low-riding bayonet style pocket clip is reversible for tip-up carry. The cross hairs in the handle center glow in the dark too.
