Preparation tools: scissors, washbasin, baking soda, white vinegar, toothbrush, toothpaste, ceramic bowl.
1. First, we need to prepare a basin and then polish the scissors. Adding a spoonful of baking soda and a proper amount of white vinegar to the basin can effectively remove some impurities on the scissors, such as rust or some dirty things. Then we will add some water to the scissors and let them soak for 5 minutes.
2. Simply soak the box, brush it with a toothbrush, and then apply some toothpaste on the blade of the scissors. Toothpaste is rich in silver film agent, which can play a good polishing role.
3. Next, prepare a household ceramic bowl, and put the blade of scissors at the bottom of the ceramic bowl for polishing. After rubbing back and forth for more than a dozen times, the blades of scissors will be particularly sharp.
Matters needing attention in grinding scissors.
It's ok if both slopes are sharpened. Be careful not to close the scissors at this time. It is also necessary to repair the two planes of scissors several times on the fine sand and oil surface of the millstone. Don't grind these two planes hard. If there is a hem, just grind it flat a little.
Lubricate the grindstone with an appropriate amount of lubricant (the oil grindstone uses oil as lubricant or water as other lubricant). Sharpening stones can make blades sharper and more durable. Put the grindstone on a flat table.
Open the scissors and make sure that the opening angle of the upper blade is the same as that of the grindstone. Grind hard from the sword of scissors to the shaft of scissors until the blade is sharp. Rubbing the grindstone along the back of the scissors can remove burrs.
