An electric manicure includes a hand-held or table-supported housing enclosing a motor and a power-driven grinding disc for fingernail trimming. A touch-plate having a slot-like opening for insertion of a fingernail forms part of the housing enclosure in proximity to the grinding disc. The touch-plate is yieldably movable towards the grinding disc, against biasing spring pressure, under the force of the finger thereon which also causes the fingernail to protrude into the slot beyond the flesh part of the fingertip. The extent of advance of the touch-plate and its spacing from the grinding disc are controllably adjustable through a lever and cam to permit preselection of fingernail trim length. Orientation of the slot in relation to the grinding disc permits a wide variety of trimming procedures. The disc may be provided with fingernail buffing means on its circumference.
