High-Performance CPM M4 Steel, Full-Flat Grind, Ambidextrous Carry

The Spyderco Tenacious CPM M4 brings elite blade steel performance to one of Spyderco’s most popular EDC platforms. CPM M4 is a high-speed tool steel produced through particle metallurgy, known for its extremely fine grain structure, high vanadium content, and exceptional wear resistance. Manufactured in the USA by Crucible Industries, CPM M4 delivers outstanding edge retention, toughness, and impact resistance.

Paired with the Tenacious’ proven ergonomics, full-flat-ground leaf-shaped blade, and stainless steel linerlock construction, this variant offers a significant performance upgrade while maintaining the reliability the Tenacious line is known for. Brown G10 scales provide a secure grip, and the four-position stainless steel clip supports fully ambidextrous carry.
