I've been kicking the idea of another straight razor (who here isn't ). I was especially interested in a Japanese razor made by Tanifuji.

I been wetshaving for years now and have seen plenty of items misrepresented/mislabeled when being sold. Like Gillette Slims being sold as Fatboys.

Now to get to my question, I've seen some Tanifuji razors bearing his name, and other razors being sold as Tanifuji but not saying it anywhere on the blade. I know he has a stamp, but some of these razors do not have his stamp either.

I suppose he made razors for different brands. Is there a list of known razors brands that were made by Tanifuji? Or what should I look for if looking to acquire one?
