The Spyderco Endura 4 C10S 3.85" Folding Clip Point Part Serrated Knife (UPC 716104004416) is a stainless-steel handled, lockback folding knife built around a VG-10 stainless steel blade with a partially serrated cutting edge. Part of Spyderco’s long-running Endura series, this configuration combines a slim stainless handle, proven lockback mechanism, and four-position pocket clip with a saber-ground, part-serrated clip-point blade designed for general utility and everyday carry use.

Blade Design, Steel, and Edge Configuration
The Endura 4 C10S features a 3.85" (98 mm) VG-10 stainless steel blade with a clip-point profile and a part-serrated (“CombinationEdge”) cutting edge. The forward portion of the edge is plain for controlled slicing tasks, while the serrated rear section is optimized for cutting fibrous materials like rope, webbing, or heavy packaging.

The blade is saber-ground from premium VG-10 steel sourced from Seki City, Japan, balancing edge retention, corrosion resistance, and ease of sharpening. A satin finish reduces glare while maintaining a clean, technical appearance appropriate for both outdoor and everyday utility environments. Spyderco’s Trademark Round Hole™ in the blade allows one-handed opening without additional studs or flippers. Spyderco+2Palmetto State Armory+2
Locking Mechanism and Structural Layout
This model uses Spyderco’s familiar back lock mechanism, positioned along the spine of the handle. When the blade is opened, the lock bar engages the tang, securing the blade in the open position until the lock is deliberately depressed to close the knife. This configuration is known for mechanical simplicity and consistent lock strength in a wide range of usage conditions. GrabAGun+1
Many Endura 4 stainless variants incorporate the David Boye Dent on the lock bar, a shallow scallop that reduces the likelihood of unintentionally releasing the lock when gripping the knife tightly. Combined with the stainless frame and screw-together construction, the C10S layout supports repeatable, serviceable operation suitable for long-term EDC use. Spyderco+2KnifeCenter.com+2
Stainless Steel Handle and Ergonomics
The satin stainless steel handle gives the Endura 4 C10S a slim, durable frame with noticeable heft compared to lightweight FRN versions. The flat stainless scales create a low-profile silhouette that carries easily in a pocket while also providing a smooth surface that many users choose for engraving or personalization.

Edge chamfering along the handle helps reduce sharp transitions, improving comfort during extended cutting. The stainless construction also offers high rigidity and impact resistance, making the handle suitable for general utility tasks where a more robust feel is preferred over ultra-lightweight materials.

Pocket Clip and Carry Options
The Endura 4 platform is known for its configurable pocket carry, and the C10S stainless model continues that pattern. A four-position reversible pocket clip allows the knife to be carried tip-up or tip-down on either the left or right side. This ambidextrous configuration lets users select a carry orientation that matches their preferred deployment technique and handedness. Cutlery Shoppe+2GrabAGun+2
A lanyard hole at the rear of the handle offers an additional retention or retrieval option, enabling attachment of lanyards or fobs when desired. This is useful for gloved use, deep pocket carry, or tethering in certain work or outdoor environments. National Knives+1
