Spyderco Endura 4 Folding Blade Knife

CPM® SPY27® is a state-of-the-art powder metallurgy stainless steel that takes the time-tested performance of cobalt-enriched VG-10 and supercharges it with niobium, nitrogen, and increased volumes 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 remarkable expression of our best-selling Endura® 4 Lightweight showcases the performance properties of CPM SPY27 with an ultra-keen, full-flat-ground blade. The satin-finished PlainEdge™ blade is paired with a lightweight fiberglass-reinforced-nylon (FRN) handle injection molded in a distinctive cobalt blue—one of the signature handle colors of our SPY27 family. All the knife’s other features faithfully consistent with the Endura 4 Lightweight platform, including a stout back lock mechanism, a high-traction Bi-Directional Texture™ pattern, and a fully configurable four-position pocket clip.
