Well Jasper, i bow to your expertize and turn the back to my silly presumption

.
Since the begining of the thread that i assumed the second word would be Portugal and only the first word was the nut to crack.
So right was author José A. Faria e Silva that, when mentioning that earlier blades were used by Officers to mount on their Regulation swords, stated that they used to reach out for either
XVII century blades shortened for the purpose, or XVIII examples that were a little shorter than the Regulation.
Dank u wel, Jasper
