In the video, a person is seen holding a piece of metal in their hand. The metal appears to be a small, circular disc with a hole in the center. The person is using a tool to make marks on the metal, creating a pattern of lines across its surface. The tool is moved back and forth, leaving behind a series of parallel lines. The person's hand is steady, and they seem to be experienced in handling the tool. The background is blurred, but it appears to be a workshop or factory setting.
