I've been using various NOS blades including Gillette Super Stainless (The Spoiler), Gillette Platinum Plus, and Wilkinson Sword. These blades are 25-30 years old and they shave wonderfully. In fact I think they are better than many of the currently produced favorites such as Derby and IP. I've yet to try Feather blades or Swedes so I can't compare the NOS blades to them. Does anyone else use these old stock blades routinely and, if so, what is your experience?
