I think there is a lot of mythology that surrounds the katana. European and other Asian swords were pretty comparable and sometimes even better than katanas. What is impressive to me, and not mentioned in the video, is that the available sources of iron in Japan is actually quite poor as in the iron sand quality is not that uniform. That they can start with such low quality material and get something like the katana is very impressive. I think the scarcity drove the innovation in techniques. That said, India and the Middle East also produced some incredible swords with various techniques. The katana has its aura partly because of its association with the samurai class. After the "sword hunt" initiated by Toyotomi Hideyoshi, wearing a sword became a status symbol because only the samurai class could have swords. In neighboring China, no weapon gained such reverence simply because in Chinese philosophy the practitioner is more important than their weapon and the best weapon is the one you have on hand. I am certain modern techniques could produce far better swords since the European and other Asian countries already could produce swords of comparable quality before the advent of modern science and engineering. I think the big difference is one of culture and philosophy. Other countries don't revere the sword as much as Japan.
