If you want the quickest possible opening for your Matriarch2, the Matriarch2 with an Emerson Opening feature is just the ticket. The integral hook on the back of the blade snags the corner of your pocket as the knife is drawn, smoothly opening the blade as the knife clears the pocket. The original Spyderco Matriarch was inspired by a request from our South African distributor for a more economical version of the Civilian. The Matriarch2 is the latest expression of that concept, combining the Civilian's aggressive blade shape and Reverse "S" edge profile with the lightweight handle construction of the best-selling Endura4. The result is a knife that provides extreme cutting performance in a convenient, lightweight package. Its SpyderEdge VG-10 stainless steel blade is scientifically designed to maximize cutting performance and its sturdy back lock mechanism, four-position clip, and Trademark Round Hole ensure unmatched carry versatility and high-speed opening with either hand.
