Scissors are indispensable items in life, so how to sharpen them when they are dull?

Scissors are indispensable items in life. If the scissors are dull, there is no need to sharpen them. You can use some life tips to solve it. Grind scissors with toothpaste, salt, rough bottom of porcelain bowl, white vinegar, sandpaper, tin foil or cans with scissors. In addition, if you use a grindstone to sharpen the knife, you need to use the thin side first, keep the knife surface with water, and water it while grinding.

Scissors are indispensable items in our life, but they rust easily when used. It's a pity to lose it, but I can't find the pencil sharpener. At this time, you need to play your own skills, and you can use some side doors to sharpen scissors.

The first method is to grind scissors with the remaining toothpaste, so that the scissors will be sharper. The second method is to put a porcelain bowl upside down on the table, sprinkle some edible salt at the bottom of the bowl to increase friction, and then pour some water. Scissors can be sharpened by rubbing repeatedly on the bottom of the bowl.

The third method is to prepare a basin, pour clean water, put scissors in it, pour some white vinegar and soak it for more than half an hour before taking it out. The principle here is that white vinegar can react chemically with iron. Then put the scissors on a porcelain bowl or grindstone and polish them repeatedly, so that the scissors can be rusted and become brand-new.

The fourth method is to prepare a can and cut a few knives on the empty can and bottle with blunt scissors. If there is no jar, you can also have sandpaper. If you cut on sandpaper, the scissors will become sharp. Or find some foil paper, fold the foil paper into several layers, and then cut the foil paper with scissors, and the scissors will be sharp.

Some people have grindstones in their bodies. What needs special attention is that if we use a grindstone to grind scissors, we should first grind the thin side of the grindstone while watering it to keep the knife surface level. Then sharpen the outer edge of the knife and smooth the inclined plane. In general, it is not recommended to grind at home, because it is easy to grind scissors.
