The Spyderco Endura 4 Lightweight 3.80-Inch VG-10 Steel Blade Signature Serrated Black Knife is one of the best-selling folding knives ever made. All members of the Endura 4 family include a four-position hook, a high-strength back lock mechanism, and Trademark Circular Hole. Released in 1990, the original Spyderco Endura and its smaller counterpart, the Delica, redefined today’s folding knife concept. They set a new standard as the first lightweight, one-handed-opening folders. The fourth-generation Endura continues to set the standard as one of the best-selling folding knives ever made. In the process, it has also spawned an entire family of variations to meet virtually every user’s needs and preferences.

Premium Construction

The direct descendants of the original model, Endura 4 Lightweights feature skeletonized stainless steel liners and an injection-molded fiberglass-reinforced nylon (FRN) handle. They come in a full spectrum of colors and a variety of different grinds, edge configurations, and blade steels. Specialized versions include one with an Emerson Opening Feature that automatically opens the blade as the knife is drawn, a blunted, red-handled trainer, and all-new, hand-dyed Zome versions with multi-colored handles.

Light and Durable

This Endura handle is fabricated with fiberglass-reinforced nylon (FRN). The FRN is a polymer mixed with glass fiber that is injection molded and formed into a sleek, textured handle, creating a lightweight yet highly-strengthened knife handle.

Secure Grip

To provide a non-slip grip, these knives are molded with the patented Bi-Directional Texturing pattern. This texture pattern consists of opposing graduated steps radiating outward from the center of the handle.

Advanced Cutting Performance

This lightweight knife includes the Flat Saber Grind blade. This grind maintains full thickness through a larger portion of the blade for increased strength and elevated cutting performance.

Customize to Your Needs

Whether you want to carry your knife tip up or tip down, on the right side or left, this knife is designed to be adaptable to your preferences.
