Any scissors and other cutting surfaces of tools will gradually become dull. You can return them to their original sharpness if the sharpening procedure is carried out correctly.
Over time, every scissors from the middle stop cutting the paper, and begin to wrinkle it. This suggests that this particular area has become blunt more than everything else. Many start sharpening right away, which is fundamentally wrong. The fact is that during operation a gap occurs between the two blades. This becomes the reason that the tool does not cut the paper, but crumples it. Therefore, you need to remove the plastic cap and gently and gently knock on the rivet with a hammer. This will reduce the gap. The main thing is not to remove it completely so that the movement of the blades remains free. After this procedure, the scissors will become better to cut, but sharpening is still necessary.
Sharpening process
In order to make the cutting surface sharp, you need to take a regular tin can. Cut the lid from this jar with scissors. This must be done so that the blades are fully engaged in length. Then they will sharpen evenly.
The cover is made of a rather tough metal, so during its cutting, the cutting surface is automatically straightened, sharpened, and burrs are removed.
Basically, it is enough to cut just one such lid. But if the tool is blunt, and this option does not give the desired effect, then it is worth using fine sandpaper. The whole process takes only a few minutes and the result is excellent.
