Beautiful example, Thomas! 
Blacksmithing of iron meteorite into a knife or tool does not eliminate so called Widmanstatten patterns. Those patterns are de facto crystals of iron and nickel that formed as the result of the meteorite having cooled very slowly (about 1°C = 1.8 °F per million years) under extremely high pressure.
