Spyderco Endura® 4 Lightweight – C10PSBK (CombinationEdge, Black FRN)

The Spyderco Endura® 4 Lightweight is one of the most influential folding knives ever created. First released in 1990, the Endura helped change the knife industry as one of the earliest lightweight, clip-carry folders. Over 30 years and four generations later, it remains one of the most trusted and widely recognized cutting tools in the world.

The C10PSBK variant features a CombinationEdge™ VG-10 stainless steel blade—partially serrated for aggressive slicing and partially plain for controlled precision cuts. The blade is saber-ground for excellent strength and cutting power, making it a versatile option for both utility and outdoor tasks.

Its lightweight yet durable FRN (fiberglass-reinforced nylon) handle is injection molded with Spyderco’s signature Bi-Directional Texture™, offering exceptional grip security in any condition. Inside, nested, skeletonized stainless steel liners add structural strength without adding weight. The reliable back lock mechanism ensures consistent, secure lockup, while the four-position pocket clip allows fully ambidextrous carry—left or right, tip-up or tip-down.

Perfect for everyday carry, professional use, or outdoor adventures, the Endura 4 Lightweight continues to set the benchmark for performance and value.
