Spyderco Endura 4 Lightweight K390 Blue Folding Knife C10FSK390

Spyderco Endura 4 Lightweight K390 Blue Folding Knife C10FSK390

Bohler-Uddeholm developed K390 MICROCLEAN to provide extreme wear resistance and the high compressive strength required for demanding industrial applications. The exceptional toughness and wear resistance of K390 as a blade steel make it especially well suited for thin, high-performance edges – including the teeth of serrated edges. The SpyderEdge versions of the Delica 4, Endela, and Endura 4 not only take full advantage of K390’s remarkable properties, but also add low-friction edge geometry and a full-flat grind. Like all members of the Spyderco K390 family, their bidirectionally textured FRN handles are molded in a distinctive blue color.
