Most of the really legendary makers especially the German ones are still in existence making cutlery but not razors. Actually you might find many of the knives with these names are imported out of the orient and they just put their names on it. I don't know what the laws in these countries dictate about how you can claim say made in Germany on a product. Many have cheaper lines and high end lines and higher end ones might be made still in the home countries.

I doubt you will find anyone beginning to make razors from scratch. remember also that most of the old companies didn't make complete razors. They bought ready made blanks and did a variety of operations on the razor and bought scales from scale suppliers. Very few did it all from scratch. To start now means probably have to do it all. very expensive to start up and get experienced people.
