Thanks for the info.
In this case I searched for the mei signature in the database (nihonto club), and the one Nobutomo I found, seems to be the only one, who signed in that way. Hence the confusion. I looked at all the signatures of the generations of Nobutomo, and not one mached, but this one from a diferent area.
I found the smith Nobutomo with the exakt same Mei signature, as the one on my sword.
The signature on the blade is 信友作 (nobutomo saku), as Ray said.
But this places the blade in Suō province, and Genji era. - https://nihontoclub.com/smiths/NOB529
The NBTHK paper places it in Kasyu (today Ishikawa).
Now I'm a bit confused.
Hello
I bought this wakizashi and would like information about the sword, the blacksmith, the age and the value. There are no papers.
Can you help me?
Thanks in advance
