What simple method is there if the kitchen knife is not sharp?

There are three simple ways to grind a kitchen knife: bowl grinding, stone grinding and double knife grinding.

1, with ball mill

First, prepare a bowl with a bumpy bottom. Put the knife at a 20-degree bump and start grinding. Don't tilt it too much, it's easy to sharpen the blade. Sharpen can only be sharpened in one direction, and it is not allowed to sharpen the knife up and down, which is easy to hurt the blade. First grind the knife forward about 20 times, then turn it over and continue grinding on the other side, which is enough for 20 times.

Step 2 grind with a millstone

Grinding with grindstone is the most traditional grinding method. Prepare a grindstone first, then put the knife on the grindstone and polish it vertically or horizontally. When grinding, use the rough surface of the grindstone first, and then use the fine surface of the grindstone to grind, so that the kitchen knife will be sharper.

3. Double-knife polishing

The easiest way is to grind two knives together. As long as two knives are crossed together, one of them does not move, and the other one is used to sharpen the knife for about 20 times, and at the same time, the blunt kitchen knife can be sharpened very sharply.
