When using a whetstone, you need to pay attention to the following points:
1. Soaking and adding water: The whetstone needs to be soaked in water and used after it is full of water. During the sharpening process, you need to continue to add water to keep the whetstone moist and prevent the blade from overheating.
2. Angle adjustment: The angle between the blade edge and the whetstone should be appropriate, generally 15 to 20 degrees. Wrong angle adjustment will cause the tool to lose its sharpness quickly.
3. Strength and posture: Keep a stable posture when sharpening the knife, hold the handle with your left hand, and hold the whetstone with your right hand. The strength should be gradually sharpened, not too large or too small, and constantly check the sharpness of the blade.
4. Number of sharpening times: The number of sharpening times on each side should be moderate, generally 3 to 5 times, to achieve the desired effect.
5. Cleaning and maintenance: After each use, you need to clean the iron filings and oil stains on the surface of the whetstone to prevent it from affecting the next use. The whetstone should be stored in a dry and ventilated place to prevent it from contacting metal or other hard objects.
In addition, when using a whetstone, you also need to pay attention to safety to avoid being hurt by the splashes produced during the sharpening process. For those who are not familiar with sharpening, it is recommended to practice in a safe environment first, and then perform actual operations after becoming proficient.
In general, using a whetstone requires carefulness and patience. The correct operation method can not only protect the knife, but also extend its service life.
