Hello all, I discovered Tsuba on my trip to Japan this year and bought 2 Tsuba at a market. I would love to know if they are genuine from Edo or Meiji period. The circular one might have a signature that is faded, but I am unsure. I tried to photograph it. The other in the shape of a bird looks to be the newer of the two. I’d also love some book recommendations on getting started. Thank you in advance!
