Sanding bezels and ring shanks over a sheet of sandpaper is a quick way to get level edges, but it’s also a good way to sand the skin off your fingertips. To prevent this from happening… Fold a small piece of paper towel and wet it with a few drops of water. Use the paper towel to grasp your metal piece as you rub it over a piece of sandpaper laid onto a smooth surface. The wetness of the towel will grip the metal so you have better leverage and will keep you from sanding the skin off your fingertips.
