Spyderco Endura 4 C10S 3.85" VG-10 Steel Folding Knife

The Spyderco Endura 4 delivers proven cutting performance with its 3.85-inch VG-10 stainless steel blade and ergonomic FRN handle design. This folding knife combines Japanese steel craftsmanship with Spyderco's signature thumb hole opening system for reliable one-handed deployment.

What Makes This Different

The Endura 4 features VG-10 stainless steel, a premium Japanese alloy that maintains a sharp edge longer than standard 440C steel while offering superior corrosion resistance. The partially serrated blade configuration provides both fine cutting capability and aggressive cutting power for fibrous materials. Spyderco's Bi-Directional Texturing on the FRN handle creates secure grip without adding bulk or weight.

Key Features

• VG-10 stainless steel blade with HRC 59-61 hardness rating
• 3.85-inch clip point blade with partial SpyderEdge serrations
• Signature round thumb hole for ambidextrous one-handed opening
• Lightweight FRN (Fiberglass Reinforced Nylon) handle construction
• Four-position pocket clip for tip-up or tip-down carry
• David Boye Dent lock mechanism for secure blade lockup
• Satin finish blade reduces glare and maintenance requirements

Field testing demonstrates the Endura 4's versatility across cutting tasks from rope and webbing to food preparation and general utility work. The 8.75-inch overall length provides substantial cutting leverage while remaining compact enough for everyday carry. Weather resistance comes from the stainless steel blade and non-absorbent handle materials that perform consistently in wet conditions.
