My main stay DE blades are currently Gillette Yellow, Derby Extra & Israeli with a batch of Wilkinson Classic in the post.
Attached a photo of some odds and ends. I'm curious to say the least to try out those two old Gillette 'Blue blades' but have to think the Gillette 'Stainless' and 'Super thin' will probably be the only blades with any life left in them.
Your Gillette Super Thin blades pictures here are not vintage blades. Those are current production; I believe out of Vietnam. I have tried a couple of them in the past, and found them to be very good quality blades.
