This limited-edition Sprint Run expression of the Manbug showcases the Carpenter Technology Micro-Melt PD#1, an air-hardening, cold-work die steel specially formulated to offer both superior wear resistance and toughness. Its advanced alloy composition is further enhanced by the CarTech Micro-Melt powder metal process, which ensures an ultra-fine, extremely homogeneous grain structure. Functionally equivalent to CPM CRU-WEAR, this high-performance steel is the heart of full-flat-ground PlainEdge blade of the knife. To make this elite Manbug even more distinctive, its blade is cloaked in a non-reflective titanium carbonitride (TiCN) coating and its fiberglass-reinforced-nylon (FRN) handle is injection molded in a deep burgundy color. Consistent with this stunning black-and-burgundy theme, its lock bar and handle hardware also sport durable black coatings.
