There's no question that the profile is a bit different from other kamisori I've seen, but I don't see evidence of honing or grinding. I'll just try honing it and see what happens.

The characters look like the tamahagane kanji to me. I can't see any other kanji with anything to do with razors that are even close to tamhagane. They aren't 100% clear, but the closest approximation for what I see say tamahagane.
