Spyderco's co-founder, Sal Glesser, designed this as one of the company's earliest fixed blades. They've revived it now as a limited Sprint Run featuring gray FRN and a full flat ground blade of CPM-CruWear. This tool steel from Crucible uses a special formula and their particle metallurgy process to create a super fine grain structure with excellent wear resistance and toughness. The knife includes a molded Boltaron sheath and versatile G-Clip attachment.
