This is a very old iron tsuba. It is a tsuba signed "Eiju Ju Kiyomitsu saku." It has well-forged iron, with a beautiful, deep black iron texture. The thick, rugged construction and well-balanced, beautiful design are wonderful. It has considerable weight. I believe it is an item from a very old era. 7.6 cm × 7.4 cm × 6.0 mm
