Through inspection of the casting process of Pu Yuan Magic Knife,this paper reveals the reason that the Pu Yuan knife cuts through iron as if it were mud and is called the magic one is that the criterion of "quench medium"-water was seriouly set in the"hardening" process and the craftsmanship of multiple-refined steel was adopted in casting.
