Scrapers work by drawing or pushing an edge across a surface to strip away unwanted layers. They are used in woodworking, decorating, cleaning, printing, farming, and many specialised crafts. In poetry the action of scraping may evoke restoration, poverty, irritation, or exposure, since it reveals what lies beneath accumulated matter. The tool can symbolise memory being uncovered, identity stripped of disguise, or harsh experience wearing a surface raw, while its repetitive sound adds tactile realism to scenes of labour.

A scraper removes unwanted layers rather than cutting deeply into the underlying material. It may strip paint, bark, glue, residue, or fine irregularities from wood and other surfaces. In poetry the process can represent restoration, exposure, poverty, persistence, or the removal of disguise. Each revealed layer may correspond to an earlier history or hidden identity. Related terms include file, rasp, plane, paint, bark, surface, stripping, cleaning, abrasion, restoration, concealment, exposure, memory, and the uncovering of what time has covered.
