Spyderco Endura 4 Lightweight Flat Ground Blue FRN Handle Scale First produced in the 1980's, the Spyderco Endura was one of the first knives to feature a pocket clip and it's light weight made it easier to carry than the sheath knives that were typical then. Now in it's 4th generation, the Delica has been tweaked and improved so now there are variations to meet nearly any users needs. The Endura 4 lightweight is distinguished by its skeletonized steel liners and fiberglass reinforced nylon (FRN) handle. This variant features a full flat ground plain edge blade of VG-10 stainless steel. The blade locks via a sturdy back lock that provides a secure lock up and allows for easy lock release with either hand. The FRN handles on the Endura 4 Lightweight feature Bi-Directional Texturing for a secure grip, and a hourglass pocket clip that can be mounted on the left or right side in the tip up or tip down position.
