If you already own a Delica or Endura, you have one of signature knives Spyderco makes. The knife you have just acquired is a bit different from the normal C10 Endura 4 and C11 Delica 4 Lightweights. The Spyderco Endura 4 Lightweight Signature Folding Knife in Orange is now available with a full-flat ground PlainEdge blade. Inside the handle are dual skeletonized stainless-steel liners which strengthen the knife without additional weight and double as an anchor for external and internal components to attach through generating more sturdiness and rigidity. The blades are full flat-ground 3.8-inch VG-10 with a thinner highly refined cutting edge and a larger 0.03-inch opening hole. Added to the blade's spine is slip resistant jimping. Phosphor bronze washers smooth out the open and close action and the clip is upgraded to a four-way tip-up, tip-down, left-or right-handed clip.

Construction

The Endura 4 sets the standard as one of the best-selling folding knives ever made. All members of the Endura 4 family include a four-position clip, a high-strength back lock mechanism, and trademark round hole. This Endura handle is fabricated with Fiberglass Reinforced Nylon. FRN is a polymer mixed with glass fiber that is injection molded and formed into a sleek textured handle, creating a lightweight yet high-strength knife handle. This knife features a blade ground with flat bevels that extend from the spine all the way to the cutting edge. This grind reduces drag during cutting and decreases overall weight. To provide a non-slip grip, these knives are molded with Spyderco’s patented pattern, Bi-Directional Texturing. This texture pattern consists of opposing graduated steps radiating outward from the center of the handle.
