There is another way of creating swords now. By incorporating, say, Swedish powdered steel (as one of Bugei's top-of-the-line katana does), the artist may create a sword that matches, or perhaps even beats the strength of the katana of Masamune's era.
The question becomes, is this improved blade the work of the forger, or is it merely access to better quality materials? Those who make decisions about such things in Japan have decided that it is merely the materials that have improved, not the forger. (again, this info is as of the 80's. If anyone has more current info, I'd love to hear it. I plan on, at some point, purchasing a shinken, or True Sword)

But for true and authentic Samurai swords, it would be better to have one from the era, than one of 440 Rockwell steel.
