Oh, the Dark Ages, how I miss the screaming!
These throwing axes were popular in the overlap of the Bronze age and the Iron age so a lot of the
techniques were a thousand years old...and brand new at the same time. And they had to be made for
thousands of soldiers so mass production has to be thought about. Heat treatment, hardness, that sort of thing
wasn't really important considering they may be thrown once in battle and never recovered.
The Knights and royalty had the finest weapons, they could afford to have them made, the front line soldier had
whatever they were issued or could scrounge. I would suspect the French cast them by the hundreds.......
