Many thanks to all for looking at this post.
As far as I have been told, the Yoshioka Ichimonji sayagaki (first one) was written by Tanobe sensei indeed. I get that some of it is about the fact that it is a Bizen Yoshioka Ichimonji blade, and some of it about the nagasa and also the period (late Kamakura). But is there anything qualitative about the workmanship of the blade?
I have no information about the second one.
Thank you again.
