ABSTRACT:
A method of making an abrading implement includes the steps of disposing a porous member for aiding in abrasion adjacent a first surface within a mold and supplying two reactive liquid components into the mold in a manner in which the two materials enter onto a second surface of the mold opposing the first surface, whereupon a reaction between the components form a raw implement of structural foam which is bonded to the porous member. Subsequent the reaction, the raw implement is removed from the mold and cut, preferably sawn, in a manner to provide an abrasive implement having a surface portion the foam exposed from the cut to aid in gripping the same by one's hand. An abrading implement is also provided by the method.
