The Endura 4 are distinguished by their skeletonized stainless steel liners and lightweight injectionmolded fiberglassreinforcednylon FRN handles. This specific version of the design includes a saberground VG10 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. The blade is supported by a sturdy back lock mechanism that locks it securely open when in use yet allows easy ambidextrous lock release. BiDirectional Texturing on the handle ensures a positive grip in even the most demanding conditions and its fourposition pocket clip can be easily configured for tipup or tipdown carry on either side of the body.
