Hello everyone! I have been doing some research on this sword. @Ray Singer translated the maker as Yasuhiro. I am curious if this is an authentic signature or gimei. Additionally i am curious about the age and school. I far from an expert, so feel free to correct me if I am wrong, but here are some things that I’ve noticed. It is suriage and probably missing some of the signature. Nagasa is 25 inches, takanoah yasurime, the hamon appears to be gunome, it’s hard to tell visualize the boshi or get a picture of it but I believe it is O-maru or Ko-maru. The tsuba is simple and without decoration. The seppa seem to be made of copper. The fuchi has some kind of decoration…..is it feathers or leaves or wheat? I have no idea what the menuki are but would love to know that. The kashira seems to be a bird…..possibly a hummingbird?
Any helpful comments, or correction would be appreciated. From my research there were 4 generations of Yasuhiro, and I would be curious which generation this work is from
also thanks to @Rivkinand @PNSSHOGUN for their help!
