There is disclosed herein an abrasive article having a cylindrical body formed of cellular plastic material having on its bottom surface a layer of abrasive material, such as used for sanding or scouring surfaces, the body being shaped to fit on the palm of a user's hand and being tall enough so that the fingers of the hand using the article cannot conveniently extend below the bottom of the body, the body being resiliently compressible so as to be indented by the user's fingers when firmly gripping the article, and the abrasive material being secured directly to the bottom surface of the body or being carried by paper or cloth which is adhesively secured to the bottom surface of the body. The top of the body may have a layer of mop-like fibrous material which acts as a cushion for the user's hand and may be used to remove dust from the article being sanded or scoured.
