I read that Heribert Wacker is the one doing the grinding for Boker. Don't know who forges them though.
Other than Dovo, TI and Boker, it's only customs makers and Chinese / Pakistani crap as far as I know.

I would love for one of the sheffield forges to start making their way into straights again. If I had the money to do so (I.e. I was rich) I would try to work together with Joseph Rodgers cutlery and start a new line of razors under their brand name again.
