When Spyderco introduced the first Sprint Run™ Shaman® combining the traditional look of brown canvas Micarta scales and CPM CRU-WEAR blade steel, they were overwhelmed by the response. Later dubbed “CruCarta,” this distinctive pairing of old-school, high-performance materials became an instant classic. The scales of all these knives are sanded smooth but left unpolished, so they will naturally patina with age and handling to develop their own unique character.
