Abrasives are used to shape or finish a workpiece through rubbing which leads to part of the workpiece being worn away. While finishing a material often means polishing it to gain a smooth, reflective surface, it can also involve roughening as in satin or matt finishes. This range of abrasives features the hand held variety but you will also find further abrasive items in the Power Tools section. (Files act by abrasion but are not classed as abrasives and can be found in their own section)
