Its not such a stretch to think that Filly got SOME of their steel from Germany. Also not a stretch to think they got it all. Did any of you guys click the link that Richmondesi provided in the beginning of this thread? The advertisement shows what appears to be a joint collaboration between Spain and Germany on the Palmera brand. So why not the Filly?
Not to mention, if the import duty on German steel had gotten too high at some point anywhere along the way, it is VERY conceivable that the Germans simply shipped the unfinished (or even finished) razors to Spain where the country of manufacture treaty might not have existed. (we know it existed for goods coming to the US, did it include goods going to Spain?) And then from Spain to the US, where Spain may have had a far more favorable tariff rate at the time.
I know they pulled the same stunt with the honey market. Cheap China honey not permitted in the US, so they shipped it to Argentina, who put it in their own barrels, and then sent it to the US as Argentinian honey.
