The video shows a person's hands using a metal file to sharpen a knife. The person is holding the knife in one hand and the file in the other, and is moving the file back and forth along the edge of the knife. The knife is being sharpened on a metal vise, which is holding it in place. The person's hands are steady and precise as they sharpen the knife. The background is blurred, but it appears to be a workshop or garage setting.
