CPM SPY27 is a cutting-edge, powder-metallurgical stainless steel that takes the proven performance of cobalt-enriched VG-10 and enriches it with niobium, nitrogen, and increased amounts of carbon, molybdenum, and vanadium. Exclusive to Spyderco, this American-made blade material offers an exceptional balance of edge retention, toughness, corrosion resistance, and ease of sharpening. This stunning expression of our best-selling Endura 4 Lightweight showcases CPM SPY27's performance properties with an ultra-sharp, fully flat blade. The satin-finished PlainEdge blade is paired with a lightweight, injection-molded fiberglass-reinforced nylon (FRN) handle in distinctive cobalt blue, one of the signature colors of our SPY27 family. All other features of the knife stay true to the Endura 4 Lightweight platform, including a robust rear locking mechanism, a high-traction Bi-Directional Texture pattern, and a fully configurable four-position pocket clip.
