The image shows a display case with four different types of knives displayed on it. The knives are arranged in a row, with the first knife on the left, the second knife in the middle, and the third knife at the bottom. All the knives have a curved blade with a pointed tip and a handle with a small loop at the end. The handles are made of metal and appear to be old and weathered. The background of the display case is a light beige color, and there is Chinese characters written on the bottom right corner.
