In 1990, Spyderco’s original Endura® helped revolutionize pocketknife design as one of the first lightweight, clip-carry folders. More than 30 years and four generations later, it is one of the most widely recognized knives in the world and still sets the standard for its breed. Current Endura 4 Lightweight models feature handles injection molded from tough fiberglass-reinforced nylon (FRN). The handles are structurally reinforced with nested, skeletonized stainless steel liners and feature a high-traction Bi-Directional Texture™ pattern for a secure grip. They are also home to a sturdy back lock mechanism and a four-position pocket clip that allows a choice of left or right-side, tip-up or tip-down carry. For steel aficionados in quest of extreme edge retention, the Endura 4 Lightweight is also available with a blade crafted from Böhler-Uddeholm’s K390 MICROCLEAN® tool steel. Available with either a modified clip-point profile or a straight-edged Wharncliffe profile, these elite expressions of the Endura 4 Lightweight also boast a distinctive blue handle color that is a signature of Spyderco’s K390 family of knives.
