This remarkable expression of the Tenacious elevates this best-selling design to all-new heights with a blade crafted from American-made CPM-M4 super tool steel. Produced by the particle metallurgy process, CPM-M4's sophisticated alloy composition, high vanadium content, and extremely fine grain structure give it exceptional wear resistance and toughness—properties that translate to outstanding edge retention and impact resistance in knife blades. This knife's full-flat ground blade is available in both PlainEdge and CombinationEdge formats and is housed in a handle featuring brown peel-ply-textured G10 scales.
