I have used the Gillette Super Thin Mejorada's before. Worked fine in a Shavette. I think they were made in Columbia? ,can't remember it has been a few years.
The Super Thin Mejoradas are made in Brazil for export to the Latin American market and are impossible or almost impossible to find in Brazil, but easier in other Latin American countries.
The Gillette Aço Azul Inox are also made in Brazil, but rumor is that they are now discontinued. They have a strong following in the Brazilian wet shaving community.
The Lord are your regular Egyptian variety, also available from US vendors.
I believe that the Fiat Lux are also made in Egypt, perhaps at the Lord factory.
