Abstract

An elongated narrow and rather thin honing tool is made from a somewhat soft metal or plastic cup holder. A tightly packed bundle of abrasive containing plastic monofilaments is inserted to the bottom of the cup holder and the cup rim is swaged inwardly to girdle and grip the bundle holding the bundle in the cup holder. The projecting tightly packed tips of the monofilaments form the working face of the honing tool. The preferred plastic for the monofilaments is nylon and the preferred transverse sectional shape of such monofilaments is rectangular, although other plastics and shapes may be used. Several methods for forming the tool are disclosed which include an insertion step followed by a swaging step. The bottom of the cup may be slightly arcuate to impart a curved working face to the bundle. The bundle may be cut or trimmed before or after insertion.
