This is a neat original Samurai era Tsuba with a Dragon Design.
The Tsuba measures 2 7/8" x 2 11/16". The raised rim is 5.5 mm thick. The design is silver tendrils with a stylized Dragon in Shakudo with gold eyes, all done in metal overlay (not inlay).
Guaranteed to be an original hand made Samurai era Tsuba, and not any kind of copy.
