Knife Handle (Kozuka)

A bronze-colored metal object shaped like a fish, oriented horizontally with head to the left, on a light gray background. The object has an open mouth with small teeth and a circular eye. Two small fins are visible on the top of the body, one near the head and one near the tail. The tail has vertical lines indicating the fin. The body of the fish has a textured, wavy pattern. The object appears to be a handle, likely for a knife, titled "Knife Handle (Kozuka)" by an unknown artist.
