The Tenacious elevates this best-selling design to all-new heights with a blade crafted from American-made CPM M4 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. The knife’s handle features brown peel-ply-textured G-10 scales.
