This is a fantastic Japanese tsuba. I just acquired it and have not, as yet, put it to shinsa but it could be from the Saotome school (but it looks too good), or the Kyo-Sukashi school. It is made of iron with a gold rim (mimi). The iron plate has been carved into the shape of a chrysanthemum flower with sixty-four petals. What makes this tsuba especially unusual and delicate it the fact that above and between each petal is a carved circle. This is unbelievable workmanship.
It does not stop there. The kozuka and kogai ana (openings) have been carved in the form of crashing waves with shakudo plates added on the nakago ana sides to protect the backs of the kozuka and kogai as they slide in and out of the koshirae.
This tsuba 2 15/16 inches or 7.5 cm measures round. The tsuba is in great condition and all of the ribs of the petals are intact. We highly recommend this tsuba for your collection.
