The term 'abrasive stuff' refers to materials that are used to remove material from surfaces by rubbing or grinding. Common examples of abrasive stuff include sandpaper (9 letters), pumice (6 letters), EMERY (5 letters), GRIT (4 letters), SAND (4 letters), and SCRAPER (7 letters). Sandpaper is a paper-like material with an abrasive surface, usually made of aluminum oxide, silicon carbide, or ceramic. Pumice is a light, porous volcanic rock that is often used as an abrasive. EMERY is a dark, granular rock composed of corundum, magnetite, and other minerals, which is also used as an abrasive. GRIT is a loose collection of small, sharp particles, such as SAND or gravel, which can be used as an abrasive. SAND is a naturally occurring granular material composed of finely divided rock and mineral particles, which is also used as an abrasive. A SCRAPER is a tool with a sharp edge or blade used to scrape or cut material from a surface.
