Strange gladius

[Youngster]

You raise a valid point, but what concerns me is the very deep pitting without any residual rust. I don't think any natural condition produces that, which is why I think that (if the blade is real) it must be over vigorous cleaning.

Also, if Decebalus is correct, it was found in Germany, wihch has no deserts (not that deserts would produce such a corrision pattern).
