Abstract
An injection molded disposable honing tool is made by an injection molding process. The tool has an elongated rectangular base from which projects an elongated section which may be somewhat smaller. The elongated section terminates in a working face. The entire tool may incorporate abrasive therein homogeneously or simply the elongated section which terminates in the working face. A shot of a plastic melt such as nylon is formed with abrasive mixed homogeneously which is then injected into a mold. For higher cost abrasive, a two shot process may be used with one shot being abrasive free. Alternatively, an abrasive-free insert may be placed in the mold before the abrasive mix is injected. The surface of the working face may be formed to act as a working face of closely packed fingers by placing patterns in the mold surface forming the working face, or subsequently cutting the working face, or a combination of both.
