Yea, there was a big discussion about it back then. I don't think it was ever resolved. But like many things, who knows. Anything is possible.

When Tosuke became ill and later died there were many blanks left over (and many of those blue sleeves which came in two shades) and many were finished by others using his name. Personally I think it possible one of his apprentices used his name to make some razors and if there are stainless versions that's where they came from.
