No beauty/first aid/camping/construction/doctor/etc. kit is complete without tweezers. They're an essential tool for many uses. If your tweezers see regular use, they're bound to get dull eventually. Dull tweezers can't grasp small objects or hair well, so you might be tempted to toss them and buy a new pair. If you have a nail file, emery board or sand paper on hand, you can use it to breathe new life into your tweezers.

Items you will need

Tweezers
Towel
Nail file, emery board or sand paper

Step 1: Rinse your tweezers under lukewarm running water for a few seconds. Dry the tweezers well with a towel.

Step 2: Hold the tweezers in your non-dominant hand and hold a nail file, emery board or a piece of sand paper in the other.

Step 3: Close the tips of the tweezers around the abrasive tool.

Step 4: Pull the tool out toward you using a single quick motion. Push it back in, and then pull it out again. The tweezers will sharpen as the blades rub against the tool's abrasive surface.

Step 5: Repeat this process a few more times. Get the best results by pulling and pushing the board in different directions.

Step 6: Check the tweezers for sharpness. If the blades are still dull, go through the sharpening process again.
