The video features a person using a screwdriver to adjust the tension on a folding knife. The person is seen holding the knife in one hand and the screwdriver in the other. They use the screwdriver to turn a screw on the knife, presumably to adjust the tension. The person's hands are visible throughout the video, and they appear to be focused on the task at hand. The background is a table with various objects on it, but the main focus is on the person's hands and the knife.
