Blixa's birth name is
Christian Emmerich which doesn't sound as cool. The comparison to Johnny Cash isn't all that far off either, from a purely etymological standpoint:
bargeld is
German for "
cash".
Blixa is a brand of pen with a good sounding name.
Despite all that, his real, legal name is Blixa Bargeld. Even his mom calls him Blixa.
