Abstract
This invention provides a method for cutting the bristles of a cosmetic brush by means of a laser beam, which comprises directing a focused laser beam on a bristle, the beam remaining focused on the bristle for a time sufficient to cut through the bristle. The increased accuracy of the laser beam as a cutting tool provides for brush designs which are unable to be achieved by conventional cutting methods.
