This limited-edition Sprint Run combines the proven performance of the Ladybug 3 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 remarkable knife are the defining qualities of the popular Ladybug 3, 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 easier to use 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 Ladybug 3 is injection molded in a distinctive burnt-orange color.
