I remember seeing a show, long long ago on swords and their forging...The part that stuck in my mind was the work and excellence that went into making the Japanese samurai swords, and how their quality surpassed just about any other sword anywhere else.
I also recall when I was a tin lid, an Uncle of mine who was a MP in the Australian Army at the end of WW2. While serving in Japan just after the war, he some how got hold of a Samurai sword, and brought it back to Australia.
My Mother ended up with it when he died, and in the early seventies or late sixties from memory when my parents noticed an add in the local paper re recovering as many of these swords as possible....After informing the advertiser of the fact we had one in our possession, we then subsequently had a call from some Japanese diplomatic/government people asking us about this Samurai sword...They inspected it and gave my Mum a large sum of money to part with it, [around $1000] simply due to the fact of how highly regarded they were and the craftsmanship that went into making them.
