As many of you know, Gillette has bought up many DE razor blade manufactures throughout the world and moved their manufacture to their St. Petersburg, Russia manufacturing facility. The razor blade brands made there are Gillette Super Stainless (Swedes), Gillette Platinum, Gillette Silver Blue, Gillette 7 OClock Super Stainless (green package), Gillette 7 OClock Super Stainless (yellow package), Permasharp, Iridium Super, Astra, Sputnik, Polsilver, Polsilver Super Iridium, Rotbart, Nacet, and Tiger. There may be more that I have missed or some have been discontinued but it is a large list. The question is, are there now any differences between the brands? Gillette could very easily change the steel, the honing and the coatings to differentiate between them, or are they the same razor blades into different packaging?
