1. A method of manufacturing an interdental cleaner, comprising the steps of:
feeding flowable nylon or polypropylene into a die; extruding the nylon or polypropylene out of an outer end of the die to form an elongated core having a solid cross-section; injection molding an interdental cleaner section, comprising a shaft and a plurality of fingers projecting from the shaft, from a thermoplastic elastomer about a first portion of the elongated core such that the elongated core extends longitudinally through the interdental cleaner section, the shaft and the plurality of fingers of the interdental cleaner section are formed by the injection molding; and, injection molding a handle portion from a polypropylene about a second portion of the elongated core such that the elongated core extends longitudinally through the handle portion.
