@Evgeny_K In my modest opinion seems to be from Belluno area like many others.
I agree with you about this one is particular because presents more edges than classical ones.
The big big problem about Venetian Republic swordsmiths has been that for many century they have been forgotten so you will find many old (and new) books that says Andrea Ferara was German, Scottish, Spanish... and many marks attributed to Solingen production or Toledo.
For example about baskethilts swords, many blades bears the name Andrea Ferara, many of them with incorrect spelling because they are imitating the original blades that comes in Scottish market in XVI century that are genuine Andrea Ferara blades.
So in Scotland they are still persuaded that this blade are made in germany, and they do not know nothing about the real story of the name.
So, about marks, it would be better to take carefully indication about provenance of some blades...
To finish, in my opinion is a Belunese blade (could we take a look to the rest of the sword?)
@Ibrahiim al Balooshi Thanks for details about his life, he has been a great scientist and engineer for sure!
@Jens Nordlunde. I have a restorer formation before than a blacksmith and I can adfirm that I find pretty hard that the indian smith were able to make an exact copy of a mark. Not only indian but every smith I know armound the world. Take a look to the fake Andrea Ferara blades for Scottish market
Cheers
