In China, a simple and effective technique to sharpen scissors in just 10 seconds went viral, surprising millions with its speed and result. This at-home method, which requires no expensive tools or prior experience, has begun to be implemented in homes around the world for its practicality.

In this article we show you how to replicate it and also other effective ways to keep your scissors always ready to cut like new.

How to sharpen scissors quickly and effectively

The technique that has gained popularity in China involves using an object that we all have at home: a glass bottle or a thick glass jar.

Step by step of the 10-second Chinese method:

1. Open the scissors completely.
2. Position the scissor blade as if you were cutting the edge of the neck of a glass bottle (the outer edge, not the sharp part).
3. Slide the scissors as if you were cutting the glass, gently, from the base to the tip.
4. Repeat this movement 5 times for each leaf.
5. Wipe the leaves with a damp cloth to remove any metal debris.

Result: The glass acts like a smooth file, bringing the scissors back to the edge in seconds.

Other Homemade Ways to Sharpen Scissors

1. Sandpaper
   • Fold a piece of sandpaper with the rough side out.
   • Repeatedly cut the paper as if you were cutting fabric.
   • Ideal for craft or kitchen scissors.
2. Aluminum foil
   • Fold a sheet of aluminum foil several times.
   • Make several cuts to sharpen and align the edge.
3. Nail sandpaper or metal file
   • Open the scissors and run each blade over the rough surface of the file.
   • I repeated about 5-10 times per sheet.
4. Knife sharpener
   • If it has a scissor slot, simply pass each blade through as directed in the device’s instructions.
5. Steel screw or pin
   • Open the scissors and simulate the cutting motion on the screw body.
   • This helps align edges and smooth out imperfections.

How to take care of the sharpness of your scissors

• Do not cut unsuitable materials: Avoid using scissors for paper on cardboard, cables or hard plastic.
• Keep them clean: Clean regularly with a damp cloth and dry well to avoid corrosion.
• Lubricate the screw: Apply a drop of oil (kitchen or machine) to keep the movement fluid.
• Store them dry: Do not leave them in damp or wet places after use.
• Use each scissors for its purpose: Kitchen scissors, sewing and paper should be kept separate.

While there are effective home methods, a good pair of scissors can last for years if you take good care of it from the start. Avoid forcing it with hard materials and apply one of these sharpening methods every time you notice a loss of sharpness. The 10-second Chinese trick is great for a quick fix… and it works!
