In the video, we can see a close-up shot of a person's hands as they are using a file to smooth out a piece of metal. The person is holding the file with their left hand and moving it back and forth along the edge of the metal. The metal appears to be a piece of steel or iron, and it has a rough texture. The file is made of a hard material, possibly a type of metal or stone, and it is being used to remove the roughness from the metal. The person's hands are steady, and they seem to be experienced in using the file. The background is blurred, but it appears to be a workshop or a garage.
