  • Patent number: 5170642
    Abstract: A reusable ear piercing earring includes a piercing pin with a circumferential groove formed therein. The groove is positioned between a pointed end of said piercing pin and a proximate end of said piercing pin. A distal end portion of the piercing pin including the pointed end is adapted to be broken off from the proximate end of the piercing pin at the groove. The circumferential groove is formed into a substantially V-shaped cross-section wherein one surface of the circumferential groove on the same side as the pointed end is inclined at an inclination angle .theta. of about 20.degree..+-.10.degree. with respect to a plane perpendicular to the axis of the piercing pin. The other surface of the groove opposite to the one surface is arcuate or round. The earring is first inserted through the ear. To reuse the earring the distal end portion of the piercing pin is separated from the proximate end of the piercing pin at the groove to provide a piercing pin with a new distal end.
