The size is slightly smaller than the broadsword. The upper end of the blade is curled into a spiral shape, which is also a bit like a nose. The prominent style is that the blade has the shape of a trunk, so it is called a trunk knife. Because this kind of knife is golden from beginning to end, it is also called golden knife. Traditionally, it is often used by older generals who play with horns-those with white or gray beards.
