Sword Guard (Tsuba)

The image is a dark gray metal object with a circular shape. The object has an oval hole on the left side and a long, narrow, vertically oriented hole in the center. There are three raised design elements on the object. The design on the top right appears to be a mountainous landscape with some gold inlays. The design on the bottom right appears to be an owl perched on a log. There are also some raised Japanese characters on the left side of the object, next to the oval hole. The background of the image is light gray. The object appears to be a sword guard, also known as a Tsuba, by an unknown artist.
