Puma Germany blade marking question

[Ruari]

A quick question on the blade marking on this Puma Germany Sportec knife.
I know the '230245' is the model number, but can anyone say what the 12/RC means?

They used to mark their blades with Rockwell hardness,maybe it's a unfamiliar scale?

Aha! Managed to find it on the Puma website.
The 'RC' means it has been Rockwell tested (there is a small punch impression on the other side of the blade).
The '12' preceeding the 'RC' means it was made in 2012.
