ABSTRACT:
A manicurist's bit for shaving away layers of an artificial fingernail. The bit comprises an elongated body portion having a right circular cross section, and has a plurality of angled knurls extending along the width of the body portion. In a preferred embodiment, one end of the body portion is concave. In operation, the bit is given a circular motion in the direction of the angle of the knurls, and is thereafter applied to the surface of the nail to be shaped. The bit shaves away portions of the fingernail, and can be used to shape the nail in the area near the cuticle, and can be used to shape the underside of the nail close to the finger tip.
