Hey Grant,
I heard Grobet USA sell files from different sources other than Swiss, some good ones from Corradi Italy and some not so good like India. Always want to find the Grobet files with the rabbit logo on the file, they're Swiss Glardon Vallorbe made.
I don't think Grobet USA is associated with Grobet Swiss.
I believe Grobet USA is abusing term "Swiss Files" the vernacular of the which is a type of file but doesn't mean it's made in Swiss. They're being a bit sneaky although they do do sell some files that are made in Swiss.
Mr. F. L. Grobet invented a machine for cutting files in Vallorbe and the Swiss company created by Grobet is now called Vallorbe Swiss and if you go to their website, they have no mention of Grobet USA as an office, distributor or dealer.
Correct me if I'm wrong on that, I was told this a while ago.
I think for the OP, if he can find the right pattern that he likes, he'll be very happy with a Swiss made one like the Glardon Vallorbe's. It's so nice to have a good super sharp hard file, its worth it. It's amazing what you can do with it.
I also believe what the OP is looking for are single cut files with safe sides as opposed to most being double cut?
