I think they found a meteorite and made some interesting stuff from it. Nothing more then that.
They would have had to develop improved smelting furnaces for that purpose. There’s no evidence they had them. If they did they would have made more iron weapons.
In a movie, James Black makes the original Bowie knife from an iron meteorite. I have no idea if it was trying to be accurate, probably not.
Anyway I don’t think he or Bowie actually invented the Bowie knife. They just developed from many other similar ones.
How cool is that... a dagger made from meteorite metal. Totally awesome.
