The image shows a set of five old, rusty knives displayed in a clear plastic display case. The knives are arranged in a row, with three on the left side of the display case and two on the right side. Each knife has a black handle with a curved blade and a small opening at the end. The blades appear to be made of metal and have a rough, aged appearance. The display case is rectangular in shape and has Chinese characters written on it. The background is a beige-colored surface.
