ABSTRACT:
An abrasive solid is composed of an organic high polymer matrix and an abrasive material dispersed in the matrix to form a solid mass, whose cutting resistance is from 2 kgf (19.6 N) to 15 kgf (147 N) so that the abrasive solid is severable into two with use of a knife, cutter or the like tool and highly effective to remove rust from any target article. Two or more of such abrasive solids each having these properties are consolidated to form an integral piece that can be trimmed into any desired shape so as to perform both the rough and smooth abrasion works for removal of rust, without using and changing any ordinary abrasive tools one after another.
