As one of the earliest fixed blades from Spyderco, co-founder Sal Glesser designed this knife, now revived as a limited Sprint Run featuring gray FRN and a serrated, full flat ground blade made of CPM-CruWear, a tool steel known for its fine grain structure, wear resistance, and toughness due to Crucible's particle metallurgy process. Included with the knife is a molded Boltaron sheath and versatile G-Clip attachment, making it a must-have for collectors and enthusiasts.
