Hi all,
Many thanks for your help. It's does make a little more sense now. I kept coming up with Atsu, shu, obi, too, but it just didn't make any sense as I was trying to correlate it to a smith.
Also, on the dedication, according to my 'Nelson's Jap-Eng character dictionary pg 36, those 5 kanji relate exactly to the translation "Amaterasu Omikami, Tenshoko.
Without the 3rd kanji it translates to Amaterasu Omikami.
Nobody, is there a difference between Amaterasu Omikami, Tenshoko and Amaterasu Sume Omikami?
I'm assuming that either way, it's a dedication.
Once again, thanks all for your help
