Spyderco Endura Lightweight K390 Blue FRN

To many savvy knife users, the Endura 4 is the perfect everyday carry-cutting tool. Enhancing it with a Wharncliffe-style blade redefines that perfection and supercharging it with K390 MICROCLEAN® blade steel raises the bar even further. Specially developed to provide the extreme wear resistance and strength needed in the most demanding industrial applications, K390 is a state-of-the-art tool steel. The full-flat-ground Wharncliffe blade of this knife takes full advantage of these properties to deliver exceptional cutting performance, edge retention, and toughness. Whether you need scalpel-like precision or sheer cutting power, its perfectly straight edge is up to the task. All other features of this knife are consistent with the time-tested Endura 4 Lightweight, including a high-strength back lock mechanism, skeletonized stainless steel liners, a four-position pocket clip, and a lightweight fiberglass-reinforced-nylon (FRN) handle molded in the signature blue color of Spyderco’s elite K390 family.
