(Note: these are instructions for sharpening tweezers that you buy at the drug store to use on your body. Tweezers for model making and detail work often require a different, sharper, more narrow point than this method will provide).
Step 1: Materials
- dull tweezers
- rough grit sandpaper (150 grit)
- fine sandpaper (400 and/or 800 grit)
- a flat thin piece of metal or glass
- a small amount of water
