Hi,
I’m doing some research on this blade and someone recommended I post pictures of it up here. Based on previous help, I think it’s koto, maybe of the Oei period, with the signature Noritsune.The only Oei Noritsune smith on Nihontoclub that I can see is of the Katayama Ichimonji school, but they have a particular slanting sakura-choji hamon, which I don’t think is present on this blade. I know the hamon pictures aren’t that clear, but I think they’re about as good as I’m going to be able to get at home. Aside from it being nailed to a particular school (which would be great!) I’m particularly interested in anything anyone can tell me about the hamon and the partial bo-hi/futasuji-hi. Oh and anything about the jitetsu would be great, but I know I’m flogging a dead horse on that, with these photos.
Thanks, Ian.
