How to restore the sharpness of your knives with aluminium foil: the trick that never fails.
Having sharp knives is essential for anyone who cooks. However, with frequent use, the blade tends to wear down and makes even the simplest tasks difficult. Although there are whetstones and professional sharpeners, there is a trick that stands out for its practicality: using aluminium foil.
Do your knives no longer cut as well as they used to? The truth is that with daily use, it is normal for them to lose their edge and become less precise. But don’t worry. This trick will solve this problem. Here’s how to sharpen them with aluminium foil.
The homemade trick with aluminium foil that leaves knives like new
Over time and with frequent use or even misuse, knives wear out. Cutting certain meats or vegetables, for example, can cause them to lose their original sharpness. While there are professional sharpeners or special stones to restore them, many opt for homemade solutions that are effective and available to everyone.
If you are going to cut meat or vegetables and you realise that your knife is not cutting properly, don’t worry, don’t rush out to buy or use another one. You can fix it in a few simple steps.
This trick has become popular because of its simplicity and effectiveness, and it does not require any special tools or technical knowledge. Aluminium foil, thanks to its thin but resistant texture, acts as an abrasive surface that helps restore the blade’s sharpness. It is an accessible and inexpensive material which, thanks to its texture and resistance, when the blade is repeatedly slid over the foil, generates a slight friction that helps to correct the surface wear of the steel.
The step-by-step process for sharpening knives with aluminium foil is quite simple, but you must be very careful.
First, take a sheet of aluminium foil and fold it several times to form a rectangle or square with several layers. Place it on a firm surface such as a table or chopping board.
Now, run the knife repeatedly over the foil, as if you were cutting it. It is recommended to do this about 10 to 15 times on each side of the blade. Finally, test the knife by cutting a tomato or a sheet of paper: if the cut is clean, the blade has been restored.
With just a few scraps of aluminium foil, you can sharpen your knife in less than 5 minutes.
Before you ask yourself how this trick works, we’ll answer that for you. Aluminium foil has a structure that, when cut repeatedly, generates friction on the blade’s edge, helping to align and sharpen its edges.
Advantages of this trick
- It is economical, as you only need aluminium foil.
- It’s quick, because you can improve the edge in just a few minutes.
- It’s safe, as long as you do it carefully and the knife isn’t excessively worn.
It’s important to note that this trick works to quickly restore the edge, but it doesn’t replace professional sharpening. If the knife is badly damaged or nicked, it’s best to take it to a specialist or use whetstones.
