I don't know about classics, but I can say that when a certain something (country/style/material) is mentioned, centain razors pop into my mind.

Some examples:
Stainless - Friodur; Swedish - Helji or Engstrom; American - Red Imps; Collectible - Ducks; Barbers - Butcher's Barbers Use; British - Greaves (don't really know why I make that association)

Maybe that's more like word association (try it, it's fun), but I think that's part of what being a "classic" is all about.
