Thank you all for the information.
Indeed it was the Japanese Sword Society, not the Club that you are all so fond of. I am aware that the Society is contraversial and also as to why as he told me this himself during our visit. To me, that does not seem to invalidate the information that he told me about the sword. Also, it is in line with what I've been told by others over the years, just in greater detail. If someone has a reason why I should not believe the information given to me than I'd like to hear it.
To the guy who mentioned he could not access the webite: The link to the photos wasn't working well becuase yahoo was limiting the amount of transfer per day and I had some real big photos on there. I've taken off the big ones so hopefully it works better now.
