Abstract
A hand knife is disclosed comprising a handle assembly, a ring-like blade housing carried by and projecting from the handle assembly, a ring blade carried by the housing, a blade drive transmission, and a blade retention assembly. The housing defines an annular blade receiving groove opening in an axially facing side. The ring blade is supported in the housing with a cutting edge projecting from the groove. The blade retention assembly comprises a flexible blade keeper extending along the axially facing housing side and about the blade and a connector for securing the blade keeper to the housing and handle assembly. The keeper is disposed in supporting relationship with the blade along the housing face diametrically opposite the handle assembly. The keeper flexes to facilitate ring blade removal and replacement.
