Bohler-Uddeholm developed K390 MICROCLEAN to provide the extreme wear resistance and high compressive strength needed for demanding industrial applications. As a blade steel, K390’s exceptional toughness and wear resistance lend themselves well to 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, they also add the low-friction edge geometry of a full-flat grind. Like all members of Spyderco’s K390 family, their Bi-Directional Textured FRN handles are molded in the distinctive blue color of the breed.

Please note: K390 is a high-performance, non-stainless steel that can rust if cared for improperly. Always make sure to clean and dry your blade after use, and apply oil or other rust-inhibiting products if needed.
