SPYDERCO C122GBNM4PS TENACIOUS CPM-M4 STEEL BROWN G10 HANDLE COMBO EDGE FOLDING KNIFE.

The Tenacious CPM M4

CPM M4 is a special purpose high speed tool steel produced by the particle metallurgy process. Manufactured in America by Crucible Industries, its 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. For all these reasons, CPM M4 is a popular material for high-performance custom blades and the specialized knives used in competitive cutting.

Unlike 8Cr13MoV and CPM S35VN, which are both stainless steels, CPM M4 is a tool steel. Its extreme edge retention and toughness come at the price of reduced resistance to corrosion. As such, blades crafted from this steel must be maintained more carefully to protect them from moisture and staining. The benefits of this elite steel, however, far outweigh the minor investment of time needed to care for it.

The Tenacious CPM M4 faithfully maintains all the proven features and benefits of the original model, including full, skeletonized stainless steel liners, a stout LinerLock mechanism, and a versatile four-position pocket clip. To distinguish it from its brethren, its handle scales are precision machined from brown G10 with a peel-ply texture for a non-slip grip. Its defining feature, however, is its blade, which is expertly crafted from CPM M4. The blade's full-flat grind gives it outstanding cross-sectional geometry and an incredibly keen edge. These qualities are further enhanced by its satin finish, which is not only attractive, but reduces friction during use.

The CPM M4 version of the Tenacious elevates this workhorse design to extreme levels of cutting performance and edge retention. In the process, it—together with the other versions of this design—parallels Spyderco's unique Mule Team project, allowing end users to experience and appreciate the performance of different blade steels in the same knife format.
