The Endura 4 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.
