The SOG-TAC has an AUS-8 stainless steel blade that is black TiNi finished with a plain cutting 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.
