Akita Shoami School tsuba decorate with aoi leafs. Made of high grade blue shakudo with hira zogan gold inlay.
I just found almost identical tsuba with Bushu School attribution. I still think it is Akita Schoami but Bushu is also a very reasonable and natural attribution for this piece.
Made in late edo period.
Size: 71 mm x 68 mm x 4 mm
