The video shows a person's hands holding a knife and demonstrating how to open it. The person's thumb is placed on the knife's handle, and they use their index finger to push down on a button located on the handle. This action releases the blade, which is then pulled out of the handle. The person repeats this action several times, showing the process of opening and closing the knife. The knife appears to be a folding knife with a black handle and a silver blade. The background is a black textured surface, which provides contrast to the knife and the person's hands.
