ABSTRACT:
A sander comprises a body member molded of polypropylene to which a soft pad member is integrally molded or directly bonded thereto. Preferably, the material comprising the pad member is of a thermoplastic elastomer material, such as Santoprene®. Significantly, when the pad member is molded directly to the body member, the pad has internal dimensions only slightly larger than the external dimensions of the body member so that, when the body member is located within the confines of the pad member, a secure fit is formed between these two members, without any space between them. Further, the respective dimensions of the body member and pad member give the sander a thick, one-piece appearance in side and end views. The pad member may also include a plurality of openings which help provide a “spongy” effect to the user, smoothing the peaks and reaching the valleys of an uneven surface upon which the sander is utilized.
