Hi all,
I recently ran into a head-scratching confusion for my blade and just wonder if anyone can share their opinion or advise on this matter.
So my blade is signed Noshu Seki junin KANEIWA and have been previously referenced in a Mino Museum Catalog and NTHK paper as Koto (Tenso era). However, it recently passed NBTHK Tokuho and was reclassified as Shinto instead.
As such, I did reach out to NBTHK for further clarification. They said since the smith is not in the Meikan, they judged from the appearance of the Nakago and style of the signature and think that it must be made in Shinto period. To add to the confusion, this specific mei is also attributed to Koto period on Nihonto Club website.
At this point, I just wonder if anyone has access to the Meikan and help me find further info on this mei. It would be of great help in resolving this annoying confusion.
