Abstract
A hand-held kitchen utensil having a manually operable rotary drive mechanism including a helical grooved spindle housed within a tubular protective sleeve. The drive mechanism is actuated by the alternate application of a substantially vertically directed downward force which slidably displaces the sleeve. Upon removal of said force, a restoring spring force returns the protective sleeve to its initial position. This reciprocal sleeve movement is effective for rotating the spindle and an attached circular blade in respective clockwise and counterclockwise directions. A plurality of arcuate support bands extend from the circular blade and form auxiliary food mixing elements. The invention also encompasses the selective utilization of interchangeable blades which can be attached for specific food processing requirements.
