Origin of the term Eisenhauer

Hello,

I want to try to answer the initial question of this thread:
Here in Germany the general explanation for blades marked "Eisenhauer" is, that their quality was tested by cut an iron nail pinned in wood in two pieces without any visual damage on the blade after this test. Some sources say that this is also the origin of the german word "Nagelprobe", but this is uncertain and there are alternative explanations.

Regards
Robin
