When sharpening the knife, the force should be small when pushing forward, and the force can be increased when pulling back. In this way, the newly sharpened blade can be prevented from being blunt due to being pushed forward forcefully. The number of pushes and pulls on both sides should be consistent.

2. Appropriate and fixed sharpening angle

If the angle between the knife and the whetstone is too large, it is easy to cause the knife marks on both sides to be thicker, so that it won’t be so long before the knife become dull again.

If the angle between the knife and the whetstone is too small, it will make the sides of the blade too thin, and make blade easier to curl and collapse.

Appropriate and fixed sharpening angle

The correct way to sharpen the knife is to hold the back of the knife with your right hand, and hold the blade with the thumb and index finger of your left hand. The method of holding the knife surface is wrong, because it can’t force evenly.
