Which item is used to wipe chalk residue off the knife edge after testing?

Explanation:
When you’re cleaning up after chalk testing, you want to remove the fine powder without adding moisture or introducing abrasives. A dry rag or cloth is the best choice because it quickly lifts and traps the chalk residue from the knife edge without wetting the metal. Water would smear the chalk and can promote rust; soap leaves a film that may attract more grime or affect the edge; a brush might push particles around or abrade the edge. So, a dry rag effectively cleans the edge while keeping it dry and ready for inspection.
