I have a friend I used to train with who was in need of some money and knew I was looking for another sword. After a while he decided to offer me his 500ish year old Koto katana. After a little research of my own, plus him showing me signs leading to it being authentic, I decided to buy it from him since I wanted a real sword and wanted to help out a friend who needed money. He did, however, offer a buy back policy in case I found it to be a really good forgery instead of being authentic.
I had this posted on Sword Buyers Guide's forum and got some pretty good info there, but they recommended I show it to you guys as well.
From what he told me about the filing pattern on the nakago (bear with me on some of these terms, I'm still learning all this new stuff) and some other things he was showing me, and what the guys on the other forum said, I've learned quite a bit of new info thus far. I've learned it's a suriage, or o'suriage but there is no signature on the nakago. It's probably just a run of the mill tachi cut down due to the government regulations of the time. The saya looks nice enough for my tastes but I don't care much for the tsuka or the tsuba. It's a Fred Lohman piece that doesn't quite fit right and is pretty wiggly. There were a couple habaki, a seppa, and another tsuba tossed in with the deal, though neither of the habaki fit it and are just silver foil wrapped around copper. However, the other tsuba has some kanji stamped into it, and they said you guys might be able to read it and know what it means.
Anyways, here are the pics:
There are all the pictures of the blade. Sorry if it's a lot to look at. I know it has a few open grain spots and that doesn't bother me. Would be cool if it was a museum quality piece, but I'm happy with a blade that has a little character. If there is anything else you guys need a picture of to get a better idea as to what I've got, I'll be more than happy to snap any pic you want.
