Origin and age of a dagger with pierced blade

[Gonzoadler]

Thank you very much, this was helpful for me. Now I found a small number of similar daggers and an old thread about such pieces:

Finally it seems to be unclear, if such daggers are brazilian, argentinian or spanish. Maybe there will be more information available in the future.
