All Endura 4 are distinguished by their skeletonized stainless steel liners and lightweight injectionmolded fiberglassreinforcednylon FRN handles. This version of the design features a fullflatground VG10 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 BiDirectional Texturing for a secure nonslip grip and a fourposition hourglass pocket clip that supports left or rightside tipup or tipdown carry.
