All Endura 4 Lightweights are distinguished by their skeletonized stainless steel liners and injection-molded fiberglass-reinforced-nylon handles. 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.
