ABSTRACT:
A honing tool characterized by an elongated rectangular cup element or holder having a bottom interior surface, a bundle of closely packed relatively short discrete generally parallel filaments secured in the holder, and a thin layer of instant adhesive securing substantially all of the filaments at one end face of the bundle to the bottom interior surface of the holder. To make such a honing tool, a measured bundle of uniformly closely packed nonwoven, generally parallel discrete filaments is formed. A holder is supported and a measured amount of liquid adhesive is placed in the bottom interior of the holder so that a thin layer of such adhesive completely covers the bottom of the interior of the holder. The bundle is then promptly driven into the holder so that all of the filaments at one end of the bundle are in contact with the adhesive prior to the curing of the adhesive. The adhesive is then cured whereby the one end face of the bundle is secured to the bottom interior of the holder.
