The culmination of years of evolution and refinement, the Spyderco Matriarch 2 with Emerson Opener and Black Blade is one of the most formidable personal-defense tools ever made. It traces its lineage back to the revolutionary Civilian™ folding knife, which was specifically developed as a survival tool for undercover narcotics officers. The Civilian’s distinctive Reverse “S” blade was later integrated with an injection-molded fiberglass-reinforced-nylon (FRN) handle to create the original Matriarch.
