Tutankhamun iron dagger: A mysterious iron dagger discovered in the tomb of King Tutankhamun has finally had its origin explained. Scientists found that the blade was forged from meteoritic iron, meaning the metal came from a meteorite that fell to Earth. The discovery helps explain how ancient Egyptians possessed iron centuries before large-scale iron smelting was developed. Highly prized and incredibly rare, this "metal from the sky" was likely reserved for royalty and served as a powerful symbol of status, prestige and divine connection.
