Gimmicky and unrrealistic suggestions.
A tomahawk is a Francisca with an extra spike on the opposite side. Take a look at the blade shapes and handle lengths buddy.
Just like a musket with a bayonet is still a musket. Adding 1 extra feature to a thousand year old design does not make it a completely new item. Europeans traded Indians Franciscas, and Indians call them Tomahawks.
What I get from your quote is that the Native Americans had tomahawks for ages and then the Europeans made steel
tomahawks to trade with the indians. Nothing to do with fransiscas or Native Americans stealing the idea lol.
You also seem to think that the16th century french used fransisca's, only that makes your point bs.
