The video shows a close-up of a wooden surface with a metal ruler placed on it. A person's hand is seen holding a metal tool, which they use to scrape along the ruler, creating a straight line on the wood. The hand moves back and forth, scraping the tool along the ruler to ensure a precise and clean cut. The wooden surface appears to be light brown, and the metal tool is silver in color. The person's hand is steady, and the action is deliberate and careful.
