Spyderco C122PSBK Tenacious 3.39" Folding Knife Part Serrated

The Spyderco C122PSBK Tenacious delivers reliable cutting performance with its 3.39-inch part-serrated blade and lightweight FRN construction. This folding knife combines the precision of a plain edge with the aggressive cutting power of serrations, making it effective for both detailed work and tough materials. The black bi-directional textured handle provides secure grip control in wet or dry conditions.

What Makes This Different

The Tenacious features Spyderco's signature round hole opening system, allowing one-handed deployment without thumb studs or flipper mechanisms. The 8Cr13MoV stainless steel blade maintains a sharp edge longer than standard carbon steel while resisting corrosion in humid environments. The part-serrated configuration allocates approximately 60% plain edge and 40% serrations, optimizing versatility without sacrificing either cutting style's effectiveness.
