1. Remember to clean the whetstone after sharpening the knife and let it dry before putting it back.
Putting the whetstone back in the box when it is wet will cause the quality of the whetstone to decrease.
2. Don't wait to sharpen the knife until it becomes dull.
Because the blunt the knives, the harder they are to sharpen.
And dull knives are more dangerous to use than sharp ones.
3. Not all knives are sharpened from a low mesh.
Whether rough grinding or fine grinding depends on the condition of your knife.
