Sebenza 21 with classic blade?

[JPR984]

quick question: I have a sebenza 21 from 08 with a classic blade with a c stamp. I know the blade profiles are the same for the classic and 21 but there is the subtle difference in the grind bevel close to the pivot end. The classic ends a bit more abruptly than the new 21 does. anyway... Im just wondering why my 21 has the classic blade and not the 21. Is this a common thing, are there many 21s with classic blades?

All the early 21s seem to be like that, I have one too. The grind begins to change in early 09 I think. It is a very subtle variation but the early 21 is my current favorite.
