Which abrasive is described as having a cloth backing and is used on curved irregular surfaces for polishing?

• A. Emery cloth
• B. Wet and dry paper
• C. Needle files
• D. Hacksaw

Answer: (A)

Conforming to curved irregular surfaces relies on having a flexible backing in the abrasive. Emery cloth uses a cloth backing with an abrasive coating, so it can bend and follow contours while polishing, giving a smooth finish on curved shapes. Wet and dry paper has a stiffer paper backing, which doesn’t grip curves as well. Needle files are shaping tools with teeth, not sheets for polishing. Hacksaw is a cutting tool, not an abrasive for finishing. So the cloth-backed abrasive designed for polishing curved surfaces is emery cloth.
