4. The cutting edge tools should be placed in the sink and gently touch the grinding wheel for sharpening, and should not be too strong and contact with the grinding wheel for too long.
5. In the actual operation of smashing tools, it is necessary to remove the on-site debris and the oxide corroded by the working face to prevent the impact of a third party.
