(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
Step 2: Prepaire the sharpener
Typically glass covered in sandpaper is used to put an edge on a metal surface because glass is typically very smooth and very flat. I used a very thin piece of aluminum sheet here because it is almost as flat and smooth as glass, and it's thinner than the glass I had lying around.
You want to choose something thin to brace your sandpaper with because that will allow you to have the tweezers in the correct position while your sharpening them.
Step 3: Sand with the rough grit paper
If your tweezers aren't in too bad a condition you can skip this step and move right on to the fine sharpening.
