The image shows a close-up of a wooden surface with a ruler and a small metal object on it. The ruler is on the right side of the image and the metal object is on top of it. On the left side, there is a black metal bracket with a small screw and a screwdriver attached to it. Next to the bracket, there are two small nails. The metal object appears to be a protractor or a level, which is used to measure the angle of a piece of wood. The wooden surface has a light-colored wood grain pattern.
