Here are some better (hopefully) pictures of the sword.
I have close up shots of the broken kissaki, also what appears to be a ware on the top of the blade toward the habaki. Also more close ups of the nakago and mekugi-ana.
When I removed the shirayasa it was not pegged to the blade; the holes where there but do not go all the way through the wood. Instead I found that the two halves were fastened to the nakago with a type of resin or something organically similar in nature. It could be ancient Elmer's for all I know.
It is interesting to me that for all the people which I have asked for advice on this matter (all online and through email), all of them have confirmed that the mei says Inoue Shinkai, yet they also say that they can't be certain of the authenticity, which is exactly what I would expect looking at pixels on a screen. None of them have had a definitive answer.
I completely understand that I am out of my depth of knowledge on the subject of Japanese swords, which is why I am here in the first place, but I think that it would be more constructive to educate me on the matter instead of leaving captious remarks.
Motorcycle forums are ruthless and I'm not known to have thin skin, but I'm not here to have a pissing contest with anyone either. So unless you have something to teach me, I'd appreciate you keeping your comments to yourself.
Cheers,
