The serrated blade is made of black finished M390MK Steel, which was produced especially for Microtech, and the handle features a RAM-LOK Bar Lock and Iconic X Button on both sides. The high strength black polymer handle contains hardened steel liner plates, which gives the knife its rigidity. Complete with a titanium backspacer and reversible pocket clip for left-hand carry.
