Spyderco Endura 4 Black Combo Edge Folding Knife

The Spyderco Endura 4 Black Combo Edge Folding Knife (brand part no. C10PSBBK) is one of Spyderco‘s most enduring and widely carried folder designs, built here in a black, partially serrated configuration. The 3.75-inch blade is saber-ground from VG-10 stainless steel and finished in a black titanium carbonitride (TiCN) coating, combining a plain cutting edge with SpyderEdge serrations for versatility on both clean cuts and tougher, fibrous materials. Fiberglass-reinforced-nylon (FRN) handles with skeletonized stainless steel liners keep the knife light without sacrificing the strength of its reliable back lock mechanism, making the Endura 4 a proven choice for daily carry, work, or the outdoors.
