Thank you for the advice! I've definitely caught the bug and am diving in head first.
I'd say my dad did pretty good by paying $75 for the 3 cheap Chinese swords that this tsuba came off of.
I thought the same, but I can't see any lines where the 2 halves of the mold would have come together. Not even in the small holes that would require an extremely small file. That, of course, doesn't mean it wasn't filed. Just that it was cleaned up well.
I received this mounted to a cheap sword and it has sparked an interest in tsubas. I'd very much appreciate any information about it that can be gleaned from the attached photos.
