The last inch of the tip Spyderco left PlainEdge for detailed cutting (think sharpening pencils). Other awesome features include: retractable carbide tip for breaking glass, attention-pitched survival whistle, carries left/right handed, tip-up by means of a tension wire clip. Blade length: 3.7″. Overall length: 8.4″. Weight: 4 oz.
