Abstract: An improved honing tool including a holder having an open sided cavity located in one side thereof, a sidewall portion extending around at least a portion of the cavity, and one or more elongated filaments of a polymeric material having particles of an abrasive substance dispersed throughout, each of the one or more filaments having an end extending into the cavity, the one or more filament ends being heated sufficiently so as to be softened or melted to conform to the shape of the cavity and intimately engage the sidewall for retaining the one or more filament ends in the cavity. The method for manufacturing the present honing tool includes the steps of applying energy to the holder to heat the holder to a temperature sufficient to soften or melt the one or more filament ends while pressing the filament ends into the cavity so as to conform them to the shape thereof, the holder being preferably heated by induction.

Abstract: A knurling tool including an elongated body member having opposite ends and a bore extending therein from one end, the bore being spaced from and acutely angularly related to the axis of the body and extending in part through the side of the body, the bore having an enlarged portion intermediate the ends thereof, an elongated roller having an enlarged annular portion intermediate the ends thereof positioned in the body bore, with the enlarged roller portion being positioned in the enlarged bore portion, the enlarged roller portion being defined by an annular side surface angularly oriented relative to the axis thereof, and a pilot member cooperatively engageable with the body member and with the roller in position to trap and hold the roller in the bore.
