Abstract

A hand knife 20, 120, 220 of the type having a ring-like rotary driven blade 26, useful for cutting meat and the like; a blade housing 24, 124, 224 for a hand knife; and an improved circular blade 26. The blade housing has a generally circular groove 38, 138, 238 in one axial end 40, 140, 240 of the housing. The groove is as wide at the open end as inwardly to allow the blade to be inserted and removed in an axial direction. The housing receives and fully encloses a ring gear portion 56 of the blade while a cutting portion 60 extends from the groove. A blade retainer 28, 228 secured to the handle acts against a radial flange 62 of the blade when tightened, to retain the blade within the groove, and when loosened allows removal of the blade from the housing without removing or loosening the housing from the handle.
