Abstract
A rotary hand knife that includes a handpiece 12, 12', 220 a ring-like housing 14 on the handpiece, and a rotary ring blade 16 supported and guided by the housing. The blade is driven by a pinion 18, 18', 18' rotated by a motor-driven flexible cable assembly 24, 24', 24'. A removable body 58, 58', 128, 258 in the handpiece is movable manually within the handpiece to control whether or not the cable drive rotates the pinion. A spring 94, 94', 94' within the handpiece yieldably biases the body to a position where the pinion is not driven and a hand-engageable member 120, 120', 120' retains the body in a position where the pinion is driven against the force of the spring when the handpiece and hand-engageable member are gripped.
