I am hoping I can get some help identifying the school, name of the style, and the age of this tsuba.
84.5 mm tall
81.5 mm wide
3.7 mm roughly at mimi
3. mm or slightly less on face
It is forged iron with evidence of folding
It has what looks like a natural black patina,
and there is curious "melted" or brushed surface to
the right and above nakago ana on both sides.
I was wondering if this could fit ko-shoami possibly?
Thanks for your help.
