I don't know Detlef, I kind of agree with Wayne. I have noticed that black oxidation is much more stable and have not had problems with it for years.

Now there is a point, however, that in order to get a proper etch for a pattern, you do have to remove the black oxidation as well.

Hi Jose,

It's chemistry, iron oxidation is always active, like said before, black oxidation isn't very fast but still active. It's different as aluminium oxidation which built a protection against further oxidation.

A proper etch of the blade could be worthwhile.

Best regards,
Detlef
