Supercharge the cutting performance of the Endura4 Lightweight format with this extraordinary limited-edition Sprint run featuring Aogami Super Blue blade steel. Manufactured by one of Japan’s leading steel manufacturers, Hitachi Metals Ltd., Aogami Super Blue combines the same high quality iron sand that has been used for centuries to make Japanese swords with state-of-the-art alloys. The result is a steel capable of extreme sharpness and edge retention. The full-flat-ground blade of the Endura4 Super Blue actually consists of a Super Blue core sandwiched between layers of 420J1 stainless. It is mated to a lightweight handle featuring skeletonized stainless steel liners, injection-molded fiberglass-reinforced-nylon scales, and a four-position clip that supports left and right-side tip-up or tip-down carry. Like all Enduras, this knife’s Trademark Round Hole™ and sturdy back lock mechanism provide ambidextrous, one-handed operation.

Note: Aogami Super Blue is a high-performance, high-carbon steel and is not stainless. It requires proper and diligent maintenance to keep it corrosion-free. Spyderco is not responsible for the corrosion or pitting of a high-carbon blade.
