The Sword of Greedy Wolf was made from neither gold nor iron, but using a wondrous material 'Spinning Ice Jade', that came from the sky, mixed together with forty-eight other materials which also did not belong to the five metals[1]. It was forged together with the flame of extreme Yin[2]. The length of the sword was four feet and two inches, and the blade was as wide as an adult's palm. The thickest part was as thick as a man's finger. It weighed 360 Jin[3], matching exactly with the degree of a perfect circle.
