Sharpening stones should be prepared on both sides and sharpened at the same time. After the knife is opened, change another piece to close it. Only one grinding mouth can't be closed, and the sharp effect can't be achieved. If you want to be sharp, you have to grind it back and forth.

2. Choose an oilstone made of oilstone.

A millstone is made of oilstone. It should feel smooth and delicate. There is no concave-convex feeling on the grindstone, and it is the right size. You should be able to put down the size of a kitchen knife without feeling crowded.

3. Hold the angle of sharpening the knife.

The angle of the kitchen knife is the key. When sharpening the knife, put the edge of the kitchen knife parallel to the knife, and the back of the knife will stand up a little and tilt a little. Hold the knife edge and turn around. When grinding, the blade must not leave during sharpening.

4. Under the natural light during the day.

Don't choose at night when sharpening the knife, for fear that the light is not good and clear, and it is easy to hurt yourself. Choosing to sharpen the knife during the day and watching the sharpness of the blade while grinding can also protect yourself from injury.

5. When sharpening the knife, take water while grinding.

Grind the knife once. It looks a little dry when you grind it. Put a watering can next to it. When it is dry, spray some water to keep the grindstone wet. The more moist, the smoother.
