All Endura 4 are distinguished by their skeletonized stainless steel liners and lightweight, injection-molded fiberglass-reinforced-nylon (FRN) handles. This version of the design features a full-flat-ground VG-10 stainless steel blade with a PlainEdge cutting edge. This slim, highly refined blade grind creates incredible edge geometry and a distal taper that reduce friction for superior cutting performance. The blade is supported by a sturdy back lock mechanism that locks it securely open when in use yet allows easy ambidextrous lock release. The handle features Bi-Directional Texturing for a secure, non-slip grip and a four-position hourglass pocket clip that supports left or right-side tip-up or tip-down carry.
