A true classic, the Spyderco Endura 4 helped revolutionize modern pocketknife design as one of the first lightweight, clip-carry folders. Now in its fourth generation, it remains a benchmark for performance, durability, and everyday carry. Built with premium materials and Spyderco’s signature ergonomics, the Endura 4 delivers exceptional cutting performance in a lightweight package.
The Endura 4 features a flat saber-ground VG-10 stainless steel blade, offering an excellent balance of strength and cutting efficiency. The blade rides on phosphor bronze washers for smooth action and includes an enlarged Spyderco thumb hole for easy one-handed opening.
The handle is injection-molded from fiberglass-reinforced nylon (FRN) with Spyderco’s Bi-Directional Texturing for a secure grip in all conditions. Skeletonized stainless steel liners provide strength without excess weight. A sturdy back lock with David Boye Dent ensures secure lockup, while the four-position pocket clip supports tip-up or tip-down, left- or right-hand carry.
