ABSTRACT:
A smoothing and cleaning tool for molded ceramics comprises an elongated main body of spring wire having reverse bends at its ends to form a pair of spaced opposed springable legs which are normally parallel to the main tool body. Fastening devices are mounted on the leg ends for securely attaching to the opposite ends of a flexible elongated abrasive cleaning pad which is freely suspended therebetween in a taut condition and which is substantially spaced from and parallel to the main tool body. When the tool is held in the hand and the pad rubbed against the ceramic article for smoothing and cleaning, the tool legs as well as the fastening devices and pad ends springingly move toward the main tool body in an amount depending upon the extent of pressure applied. The direct pressure applied to the freely suspended pad is thus absorbed by the springable legs through the fastening devices.
