The video shows a person using a metal tool to sharpen a piece of metal. The person is holding the metal tool with one hand and using the other hand to sharpen the metal. The metal tool appears to be a file or a grinder, and the metal being sharpened is a flat, rectangular piece. The person is moving the metal tool back and forth along the edge of the metal piece, presumably to smooth out any rough spots and create a sharper edge. The background is a workshop setting with various tools and equipment visible.
