Spyderco

All Endura 4 are distinguished by their skeletonized stainless steel liners and lightweight, injection-molded fiberglass-reinforced-nylon (FRN) handles. This specific version of the design includes a saber-ground VG-10 stainless steel blade, a PlainEdge cutting edge and an Emerson Opening feature. This integral hook on the spine of the blade snags the pocket as the knife is drawn to quickly and automatically pivot the blade open. Invented by renowned custom knifemaker Ernest Emerson, this patented device is licensed for use by Spyderco. The blade is supported by a sturdy back lock mechanism that locks it securely open when in use yet allows easy ambidextrous lock release. Bi-Directional Texturing on the handle ensures a positive grip in even the most demanding conditions and its four-position pocket clip can be easily configured for tip-up or tip-down carry on either side of the body.
