Spyderco Matriarch2 with Emerson Opener Feature, unique S Blade shape, Black FRN-SpyderEdge. The Matriarch2 combines the extraordinary cutting power of our Reverse "S" blade profile and SpyderEdge serrations with the blindingly fast deployment speed of the patented Emerson Opening feature. The result is an amazingly swift and potent cutting tool that is ready for anything. As the knife is drawn from tip-up carry, the Emerson Opener snags on the mouth of the pocket and automatically opens the blade as it clears the pocket. Originally developed by renowned knifemaker Ernest Emerson, Spyderco is licensed to incorporate this remarkable feature into selected Spyderco designs. By Spyderco.
