If your scissors have lost their edge and no longer cut well, you can restore them with a simple but effective trick: use the rounded end of a drill bit along with WD-40. This technique is quick, easy, and requires no specialized tools.

Why does this method work?

The rounded part of a drill bit has a smooth, metallic finish that acts as a sharpener as it slides over the edge of the scissors. Additionally, WD-40 helps reduce friction and remove residue, leaving a cleaner, longer-lasting edge.

How to sharpen your scissors with this trick

🔹 Materials needed:

✅ A metal drill bit (preferably 6 mm to 10 mm thick)

✅ WD-40 or any multi-purpose lubricant

✅ A cloth or absorbent paper

Step 1: Apply WD-40 to the scissor blades

Spray a little WD-40 on both blades of the scissors. This will help reduce friction and make sharpening easier.

Step 2: Use the round part of the drill bit

Open the scissors and place the rounded part of the drill bit between the blades. Then, close the scissors and slide them as if you were cutting the drill bit. Repeat this motion about 15 to 20 times.

🔹 Tip:  Use a carbide drill bit (HSS steel) for best results.

Step 3: Clean off the metal debris

After sharpening, clean the scissors with a cloth to remove any sharpening residue and excess WD-40.

Step 4: Test the edge

Cut a piece of paper or fabric to check if the edge has improved. If necessary, repeat the process a few more times.
