  • Patent number: 5323538
    Abstract: A device for punching holes in artificial fingernails comprising a piston-cylinder unit having a cylinder wall with an aperture in it extending across the whole of the cylinder. The aperture is banana-shaped in cross-section and wider than the internal diameter of the cylinder with the convex side of the aperture facing the piston. The pointed end of the piston has a sharp knife-edge. The hole punch is operated by holding it between the thumb and index and middle fingers and pressing, causing the pointed end of the piston to travel past the curved cylinder-wall aperture in which the artificial fingernail to be perforated has been placed.
