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.
