I notice it doesn't mention razors. I still wonder if he didn't contract those out to a major German maker especially since it has that common style number. seems as though they would obviously make them in house but then people think it obvious that a skilled knife sharpener would by default be good at honing razors so...

Well I think at least the blanket might have been coming from Germany. 52 was a typical number that for example Puma has used quite often. Could also be ground in Germany, but eastern Europe did have very good grinders by their own, especially Hungary but also Poland.
