Maintenance of cutting tools:
Gently wipe off the residual oil and dust on the knife body with cotton towel cloth, flannel or deerskin, and then apply a little wiping oil on the knife body with cotton yarn evenly. After three minutes, the original cotton cloth was wiped back and forth vigorously, with the purpose of removing impurities on the surface of the leaves and promoting the chemical changes of phosphonium and calcium. If the knife is not kept every day or the living place is wet, it must be coated with a thin layer of antirust oil before sheathing to avoid contact with air.
Put a long towel on the table, put the blade flat on it, wrap a small piece of wood with cloth or leather, and rub it back and forth with the flat side to make it slightly warm. When there seems to be oil but there is no oil, apply a little powder on the blade, and then continue to rub it for about a quarter of an hour.
