John, Jean,
:D Ok! Now, At least this matter is solved.
What do you think about the shapes? Futsu, funagata, kijimono etc, and the tips, kuri-jiri, hagari, kiri... were all of them common in Edo Period? Do you think there was a prefered shape in particular?
I will assume the size 69,69cm for nagasa as the standard, do you agree?
I have this doubts mainly because I am assembling a Banzashi katana, I would like to make something "historical".
The next step is the koshirae...
Thanks dear friends, you are helping me a lot.
