Advanced Steel, Iconic Form. The trusted Endura, supercharged with SPY27.

The Spyderco Endura 4 Lightweight in Cobalt Blue CPM-SPY27 brings cutting-edge metallurgy to one of Spyderco’s most trusted platforms. Developed in collaboration with Crucible Industries, CPM-SPY27 is a proprietary American-made steel that enhances the proven performance of VG-10 with added niobium, nitrogen, and vanadium.

The result is a blade that excels in edge retention, toughness, corrosion resistance, and ease of sharpening. This Japanese-made variant pairs a full-flat ground satin-finished blade with injection-molded FRN handles in signature cobalt blue—lightweight, durable, and unmistakably SPY27—with reliable lockback security and versatile carry options.
