I found some info here on nihontocraft is this the kunisada that made my sword?
I mean the mei on my sword is Kawachi Daijyo Fujiwara no Kunisada.
And as someone wrote earlier
KUNISADA KAWACHI NO DAIJÔ [KANBUN 1661 IWASHIRO] SHINTÔ CHÛSAKU
He was the tôshô of Aizu, his initial mei was KUNISADA [TN], and he died
in the last year of Kanbun (1673).
Signature: KAWACHI NO DAIJÔ KUNISADA
KUNISADA KAWACHI NO KAMI [JÔKYÔ 1684 IWASHIRO] SHINTÔ CHÛSAKU
He is called Furukawa Magodayu, and he died in Genroku Ninen (1689). (Wazamono)
Signature: KAWACHI NO KAMI FUJIWARA KUNISADA
Wich one of them could it be?
The mei has DAIJÔ in it but kanetoyo also wrote that he was called Furukawa Magodayu.
If antone could help me with this i will be really thankfull.
I have also bought my first book now its The Japanese sword by Kanzan Sato, hopefully i will have it in my mail this week.
