I posted this a few other places and was told to post it here.
I purchased this sword (blade only) at a public auction a few years ago. The entire piece is about 25 1/8 inches long. The blade itself is 20 1/4 inches long and the width measures from about 1 1/8 inches at the widest to about 7/8 inches. There is writing on both sides of the tang. Unfortunately, on one side the writing is applied in a red material which has become faded and illegible near the bottom. I'm told that the maker is Fujiwara Nagayuki and the sword is somehow associated with the Tanzan Jinja. Any information regarding this maker or the sword would be greatly appreciated, especially regarding the age, style, use, and how it is associated with the shrine. Also, I'm not looking to sell it but just out of curiosity what is a blade like this worth? Thank you for your help.
