In the video, a person is seen holding a small wooden tool in their hands. The tool has a brass-colored knob on top and a small hole in the middle. The person is using the tool to adjust the position of a wooden ruler. They place the tool on the ruler and turn the knob, which seems to move the ruler's position. The person's hands are steady, and they appear to be experienced in using the tool. The background is blurred, but it seems to be a workshop or a crafting area.
