This limited-edition Sprint Run combines the outstanding functionality of the Manbug Lightweight with a special laminated blade made from HAP40 and SUS410 steels. The center layer of the full-flat-ground blade is made from HAP40—an advanced high-speed tool steel produced by the powder metallurgy process. Enriched with tungsten, molybdenum, vanadium, and cobalt, HAP40 boasts exceptional toughness and high abrasion resistance. This high-performance core is sandwiched between layers of SUS410—a martensitic stainless steel that gives the finished blade increased strength and improved corrosion resistance.

All the other features of this amazingly compact cutting tool are the defining qualities of the popular Manbug Lightweight, including a fiberglass-reinforced-nylon (FRN) handle with Bi-Directional Texturing™, a sturdy back lock mechanism, and a Trademark Round Hole™ in the blade that is much more user friendly than the nail nick of a conventional pocketknife. Like all other members of Spyderco’s HAP40 Sprint Run family, the durable FRN handle of this Manbug Lightweight is injection molded in a distinctive burnt-orange color.
