Abstract
A hand knife 20, 120, of the type having a ring-like rotary driven blade useful for cutting meat and other suitable products; a blade housing 24, 124, 224 for a hand knife; and a circular blade 26, 126. The blade housing has a generally circular groove 38, 138, 238 to receive a ring gear portion 56, 256 of the blade while a cutting portion 60 extends from the housing. One arcuate wall portion 38b, 138b, 238b of the housing is frusto-conical and faces a similarly contoured peripheral portion of the blade ring-gear. In the preferred construction the housing recess is formed by a cylindrical wall that surrounds the ring-gear portion of the blade and by a frusto-conical wall that is encircled by the ring-gear portion of the blade. A blade retainer 28, 128 secured to the handle acts against a radial flange 62, 162 of the blade when tightened, to retain the blade within the groove, and when loosened allows removal of the blade from the housing.
