Well, thanks for your help, I do appreciate it. Maybe you’re right, maybe it is Shinto. In some ways that may be a good thing, it means I’m less inclined to send it to Japan for polishing which would be a head ache removed. I mainly wanted to be sure I wasn’t sending a rare and special blade to the wrong person. If it isn’t very special it gives me more scope.
I still have a hard time buying it’s Shinto though, but that may be wishful thinking. The steel is quite blue which suggests to me older rather than newer, O suriage which maybe isn’t definitive either way and where you see a wide nioi guchi, I see poor photography as on the blade itself it looks narrow and nie to me. I’m not sure I see utsuri either, just poor photography. But it does look uniform and featureless, (which is one of the reasons I like it), although a lot of that could be the poor polish, it looks like some of it was done with 80 grit. I can’t say I’ve ever seen a Shinto blade that looks like this, but I have seen various koto blades that are reminiscent. My current wishful thinking favourite is mihara although I am probably wrong. Who knows, I could probably convince myself of anything right now.
