Detailed explanation of blunt knife precision grinding method:

1. Rough grinding: Place the blade vertically into the rough grinding mouth (close to the handle slot), and pull it back about 5 times with slight force;
2. Fine grinding: Place the blade vertically into the fine grinding mouth (middle groove) and gently pull back about 3 times;
3. Fine grinding: Place the blade vertically into the fine grinding mouth and gently pull back about 3 times.

• Due to differences in the material and angle of the blade, if the grinding effect is not satisfactory, it is recommended to continue rough grinding and gradually increase the force to observe the effect (even if it can be pulled more than ten times in one direction). The blade should be shaped for the first time, and it will only be sharp after successful shaping, and there is no need to shape it again in the future.
