Rings & Things has a 2″ long curved burnishing tool used to burnish malleable metals in jewelry making for $2.50. If it seems a little on the strange side, it will only seem so until you require its services.
The burnishing tool is one of the only ways to “erase” a deep scratch in a piece before polishing. While sanding removes metal, the burnishing tool moves metal, smearing it if you will, so you can often make a pit or scratch disappear. Burnishing tools are also used when setting stones to get the bezel around the stone to shrink to fit and hold the stone securely.
