The video shows a close-up of a knife being held in a person's hand. The knife has a silver blade and a black handle. The person is holding the knife with their thumb and index finger, and they are using their other hand to run their thumb along the blade. The blade appears to be sharp, as it cuts through the skin of the person's thumb without any resistance. The person's thumb is bleeding slightly from the cut. The background is blurred, but it appears to be a dark-colored surface.
