Correct methods and skills of sharpening knives

The correct sharpening methods and skills are introduced step by step as follows:

1. Prepare the tools to be ground and a grindstone with coarse stones on both sides.

2. Next, soak the millstone in water for ten minutes, so that the millstone can fully absorb water.

3. Put a towel on the chopping board to prevent the millstone from sliding.

4. Choose rough stone edges and polish them vertically.

5. Stick the blade to the grindstone, drag it back and forth, and touch the surface of the blade with your fingers to feel the temperature of the blade.

6. When the blade temperature is too high, stop the action and sprinkle water on the blade position to reduce the blade temperature.

7. Sharpen the knife on one side for 15 minutes, and then sharpen the knife on the other side in the same way.

8. Next, grind the blade with fine stone surface and adopt the method of transverse grinding.

9. Gently pull and push the grinding blade back and forth for polishing, and the blade and grindstone keep an angle of 5, and the duration of both sides is 15 minutes.

10, pick up the knife, and when the blade is out of sight, the sharpening work is completed.
