What do you use to remove paint, debris or material from the knife edge?

• A. A wooden Block
• B. 320 grit sandpaper
• C. 320 grit sandpaper or aluminum oxide cloth
• D. Nails and hammer

Answer: (C)

The idea is to use a mild abrasive that can lift paint and debris from the knife edge without removing metal or causing damage. A 320 grit abrasive provides a controlled, fine cut that can remove surface paint and residue without taking off too much material. Aluminum oxide cloth offers the same capable action but with a flexible fabric backing, making it easy to follow the edge and contours. Either option works, depending on what's available. A wooden block by itself has no abrasive action, so it wouldn’t remove the paint effectively. Nails and hammer aren’t abrasive tools and would risk damaging the edge. Use light, even strokes and clean away residue as you go.
