Spyderco C90FP2K390 Stretch 2 (K390, Drop Point, Satin, Blue FRN, Back Lock) Lightweight Pocket Knife

The Spyderco C90FP2K390 Stretch 2 K390 MICROCLEAN is a high-performance folding hunting and outdoor knife developed from decades of real-world feedback from experienced outdoorsmen. Designed for demanding field use, it focuses on extreme edge retention, cutting efficiency, and secure handling in rugged environments.

At its core is a 3.48″ full-flat-ground blade made from K390 MICROCLEAN® particle metallurgy tool steel. Engineered for industrial-level wear resistance, toughness, and compressive strength, K390 delivers exceptional edge retention and cutting performance, making it ideal for heavy outdoor and hunting tasks where long-lasting sharpness is critical.

The straight-spined blade profile enhances control and slicing efficiency, while the full-flat grind improves cutting performance across a wide range of materials. The blade is supported by a robust back lock mechanism housed within a lightweight FRN (fiberglass-reinforced nylon) handle.
