First introduced in 1990, the Spyderco Endura was one of the first lightweight, high-performance, one-hand-open pocketknives ever developed. A consistent best seller, it has evolved steadily over the years through Spyderco's CQI (Constant Quality Improvement) process. The Endura 4 features enhanced ergonomics, screw-together construction, and a four-position clip for versatile carry options. Its fiberglass reinforced nylon handles are molded with Bi-Directional Texturing for improved traction and control and are supported by dual skeletonized stainless steel liners. The liners increase structural strength without adding weight and provide a framework to anchor all external and internal components. Its VG-10 blade is flat saber-ground with a stronger tip and larger 13mm opening hole. This version is also black titanium carbonitride coated to reduce reflection and provide increased corrosion resistance. Phosphor bronze washers ensure a smooth action, and textured jimping on the spine guarantees positive control during use.
