The secret to the ancient swords from Japan was that, during forging, they would quench the hot blades in the bodies of peasants, prisoners, or slaves. The proteins from the bodies gave the steel properties that made it harder, once cooled and easier to fold and work with while hot.
It took the west a very long time to catch up. It was discovered that simply putting animal pelts into the quenching water would accomplish the same effect.
Anyway, that was the "magic" behind Japanese swords.
