In the 1980s, the original Spyderco Endura set a new standard as one of the earliest lightweight clip-carry folding knives. Today, it remains one of our most popular models, continuing to lead the way for knives in its class. Now in its fourth generation, the Endura 4 has evolved to offer a diverse range of variations tailored to meet the diverse needs and preferences of users. All Endura 4 Lightweights feature skeletonized stainless steel liners and injection-molded fiberglass-reinforced-nylon (FRN) handles. This particular version boasts a robust saber-ground VG-10 stainless steel blade with a partially serrated CombinationEdge, enhancing its cutting efficiency on fibrous materials. The blade is secured by a sturdy back lock mechanism, ensuring it stays firmly open during use while allowing for effortless ambidextrous release. The handle is equipped with Bi-Directional Texturing for a secure grip in challenging conditions, while its four-position pocket clip provides versatile carry options, tip-up or tip-down, left-handed or right-handed.
