Endura® 4 FRN Grey Emerson Opener
In the 1980’s, the original Spyderco Endura blazed a trail as one of the first lightweight clip-carry folding knives. Today it remains one of our most popular models and continues to set the standard for all other knives of its breed. Now in its fourth generation, it has also inspired a broad range of variations to meet virtually every user’s needs and preferences.
All Endura 4 Lightweights are distinguished by their skeletonized stainless steel liners and 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.
