Specifically developed as a survival tool for undercover narcotics officers Lightweight handle Features supercharges the design with an integral hook on the back of the blade that automatically opens it when the knife is drawn from the pocket The Matriarch 2 combines an aggressive VG-10 stainless steel Reverse S blade with the lightweight handle of Spydercos best-selling Endura 4. Ernest Emersons patented Emerson Opening feature supercharges the design with an integral hook on the back of the blade that automatically opens it when the knife is drawn from the pocket.
