Don't take this as gospel though, since the appropriate WWII records could be lurking behind a paywall I'm not privy to.
However, I cannot turn up any search hits for Clauss-made straight razors beyond 1918. They may well have made them, but if they did, they didn't advertise them. They got hammered in the 1920's for selling razors stamped with 'Sheffield' that appear to have been produced... Somewhere. The company rep claimed that in the natural course of their business they bought out a warehouse that had a whole bunch of bare razor blades in it, so they naturally stuck scales on'em and sold'em to the public, but they really didn't know if what was stamped on them was true or not.
The FTC smacked'em around a little and told them not to do it anymore.
There is a 1937 Annual Report on Munitions which mentions Clauss several times, but the book isn't fully available and I can't tell what was being purchased from them (not a whole lot of whatever it was, as the maximum charge listed was $26,622.68). By that time, they were regularly advertising and selling safety-razor blades.
