I bought my first Tsuba and am looking for someone knowledgeable to give me an idea of its authenticity. This was bought off of an expat collector in Japan who has a business sourcing and refitting Japanese swords. There was no information on it he was able to provide and it does not have a signature. I do not know the material, although the places where the patina has worn away shows a copper color. I know nothing about tsubas and it felt like a bit of an impulse buy. Really, I would be happy with the purchase just knowing if it is authentic, and if a craftsmen some long time ago put their labor into it. Thank you for your help
