Here is the actual name/owner of the Verona, VA industrial maker of blades you referred to. As of 2015— this acquisition of the American Safety Razor Co. a very old company in US history. Devolved to industrial blade production. You can get blades direct from them as you stated.
Oops, double post reply. Remove if you would, thanks.
