Combining the functional, performance-based design of classic Spyderco knives with the patented Emerson blade-opening feature, the Endura 4 plain-edge folding knife is ideal for a host of applications. The Emerson opener is the Endura's most distinctive feature, with a hook that curves out of the top of the knife blade. Each time you remove the Endura 4 from a front pocket, the hook will catch the pocket's edge, quickly opening the knife blade so it's ready to use. The Emerson opener makes this a terrific knife for fishing, hunting, and other sports where one-handed use is crucial. You can also take the knife out of your pocket without engaging the Emerson hook by pulling it straight up and out, with your fingers placed on top of the closed blade. 

Functionally, the Endura 4's VG-10 steel blade is flat saber-ground with a strong tip and a large 13mm opening hole. Users will also love the gray fiberglass reinforced nylon handle, which is molded with Bi-Directional Texturing for traction and improved ergonomics. And inside the handle are dual skeletonized stainless-steel liners, which strengthen the knife without adding additional weight. This also creates an anchor for attaching external and internal components. Other features include screw construction for easy cleaning and adjustment; slip-resistant jimping on the blade's spine; and phosphor bronze washers that smooth out the open/close action.
