Before civilizations mastered the art of forging steel, meteoric iron was among the hardest metals known, and the best for making weapons. Egyptians valued meteoric iron more than gold; King Tutankhamen was buried with several gold daggers but only one of iron. Meteoric iron has a high carbon content, which was difficult to duplicate even by Norse times. As such, a meteoric iron weapon that could hold its edge for so long was considered magical. The Norse sagas mention a warrior who straightened his sword blade with his foot, suggesting that the iron the Norse typically used was of fairly poor quality.
