Spyderco C122PSBBK Tenacious 3.39" Folding Knife Black Oxide

The Spyderco C122PSBBK Tenacious delivers reliable cutting performance with its 3.39-inch partially serrated blade and lightweight FRN construction. This folding knife combines practical design elements that make it suitable for everyday carry, outdoor activities, and general utility tasks. The black oxide coating provides corrosion resistance while maintaining a low-profile appearance.

What Makes This Different

The Tenacious features Spyderco's signature round hole opening system, allowing for one-handed deployment even when wearing gloves. Unlike traditional thumb studs or flipper tabs, the 13mm SpydieHole provides consistent opening action regardless of hand position. The blade geometry combines a fine edge for precision cutting with serrated sections for fibrous materials, eliminating the need to carry multiple cutting tools.
