Just got this little treasure from an antique store in my travels for a price that made me very happy. It looks unused to me except for the fact that a few blades are missing from the pack. I believe it to be 1955 (A-2).

Questions: Are these blades worth using? What's the difference between a Diplomat and an Aristocrat? Being newer, was this supposed to be some sort of improvment over the previous? They look the same to me except for subtle variations in knurling.
