I rather often see these vintage Blue Gillette blades on ebay, I suppose they are from early 60s, are they any good?
I use vintage Schick and Gillette Blades and get great shaves , Spoilers are one great blade !! Stainless , no carbon blades.
I would rather ask has anyone ever had a good shave from a 70s or earlier vintage blade?
Me? No. The vintage stuff all seems to explain why cartridge razors stole the market in the 70s.
I'm sorry for your experience with them. Most likely you used some that have degraded. I only use vintage blades, mostly stainless but a few pristine, well cared for carbons as well. Blades were made to a significantly higher quality back then because the market they targeted were first world, western men of middle to upper class who had the money to spend and could afford the best. Today the market for double edge wet shaving is probably 85% or higher third world. They couldn't afford blades made with the same quality. Hell, most of us would balk at the prices they'd have to ask now. Look, I'm holding a 15 pack of Gillette Platinum Plus from 1970 marked at $2.49. If you only account for inflation the price for these today would be $16.52! And that's if relative costs of labor and materials stayed the same, which they haven't. Another "Tell" is the big difference in longevity, add the fact that if you scour all the different forums on shaving and collect opinions, something a little higher than 9 out of 10 people who've tried vintage blades in anything close to original shape pronounce them the best they've ever used by far.I would rather ask has anyone ever had a good shave from a 70s or earlier vintage blade?

I am not sure if the quality was better. Yes, they need now produce cheaper blades, but the machinery and technology got much better. I have one Gillette blade from 1920something. It is not flat. It shows typical production defects of wrong roll milling. But hardened carbon steel is harder than stainless. So the material might be a reason for longer durability.
I have a reprint of a German catalog from 1912 from a store similar to Sears & Roebucks. It has lots of no-name copies of Gillette razor sets and even one closed comb razor. The price of a no-name blade is 0.20 Mark. In Germany we have official statistics of the average annual income since 1891. I think it is the best way to compare prices here in Germany. ( Durchschnittsentgelt – Wikipedia - https://de.wikipedia.org/wiki/Durchschnittsentgelt ) 0.2*(39000/1164) = 6.70 Euro = USD 7.40 per blade. So one blade in 1912 cost as much as 100 blades now.
