This is a later model of the Mini Pentagon with AUS-8 steel (earlier versions had AUS-6 steel made in Seki Japan). The compact version of the original SOG Pentagon, the Mini Pentagon is a serious back-up knife that easily conceals in boot or vest. Extremely lightweight and comfortable to maneuver, the Mini Pentagon also offers the instant choice between a straight or serrated edge for multiple cutting tasks. Twin thumb notches on the blade enable accurate blade orientation and downward control. Like its big brother, the Mini Pentagon has aggressively checkered, flared Kraton handles for confident gripping as well as sensational feel and balance.
