Nulldevice-my bad, I wrote this not realizing you posted a different sword bc my wife's talking at same time, so I'm gonna blame her lol. I'm new to this forum, please be patient with me. I'm talking about the katana that became Kuroda Yoshitaka's, it has a bizzare saya where half is red or brown, and the bottom looks gold and spikey. I found the one I mean, but not the koshirae. If I didn't know it's provenance, I might think this was Shinshinto as they tried to find and restore lost techniques, so I find it at times really difficult to accurately access Nihonto, but especially with pictures alone. I'm glad their are groups like this. I wish I sought out advice online a decades ago, when I could've probably afforded a few decent Mumei Nihonto's for a the money I spent on Hanwei swords. Not that I don't still love some of them.
