Spyderco Endura 4 Lightweight Features The Spyderco Endura 4 Lightweight is built around CPM SPY27 a steel developed in close cooperation with Crucible Industries and proprietary to Spyderco. This powder metallurgy formulation takes the time tested performance of cobalt enriched VG-10 and enhances it with niobium nitrogen and additional carbon molybdenum and vanadium producing a blade material with an exceptional balance of edge retention toughness and corrosion resistance. The full flat ground 3.8 inch drop point blade carries an ultra keen plain edge with a satin finish giving it both a clean look and excellent cutting performance. At 8.7 inches overall the Endura 4 remains compact enough for everyday carry while still offering a usable blade length for most daily tasks. The handle is injection molded from fiberglass reinforced nylon in a distinctive cobalt blue one of the signature colors of the SPY27 family giving the knife a lightweight yet durable grip. A reliable back lock mechanism secures the blade firmly open during use and closes with a confident positive action. All other features on this model remain faithfully consistent with the time tested standard Endura 4 ensuring the same trusted ergonomics and carry profile. Manufactured in Japan to Spyderco s exacting standards the Endura 4 Lightweight in CPM SPY27 is a standout choice for anyone seeking premium steel performance in an everyday carry folder.
