Spyderco Endura 4 Wave Folding Knife

The Endura 4: A Cutting Standard

Spyderco's Endura 4 represents decades of refinement in folding knife design. This is a knife that has earned its reputation through consistent performance and thoughtful engineering.

Blade and Edge

The 3.81" blade is ground from VG-10 stainless steel—a Japanese steel known for holding an edge while remaining relatively easy to sharpen. The plain edge provides versatility for general cutting tasks, from food preparation to utility work.

Opening System

The Emerson Wave opener is the standout feature here. This integral hook on the blade's spine catches your pocket as you draw the knife, automatically pivoting the blade open. For those who need one-handed deployment, this is a genuine advantage. The system is intuitive and works reliably.

Handle and Grip

The lightweight FRN (fiberglass-reinforced nylon) handle keeps weight minimal without sacrificing durability. Skeletonized stainless steel liners provide structural support while maintaining the knife's low profile. Bi-directional texturing on the handle ensures positive grip control, even in wet or demanding conditions.

Carry and Operation

The four-position pocket clip accommodates tip-up or tip-down carry on either side of the body. The ambidextrous back lock mechanism is secure and intuitive—it locks the blade firmly open during use and releases easily from either side.

A Proven Design

The Endura 4 is not a novelty. It is a working knife trusted by professionals and enthusiasts worldwide. If you need a reliable, well-designed folding knife, this is a logical choice.
