Matt,
Wow, in a minute you have done what I couldn't do in 3 days of research, being new to this so you can imagine my appreciation.
Then, the blade would be oil quenched and machine made? Not that I WANT to come to that conclusion... But it is really neat to assign the character to the blade as you have. Kind of livens the piece..
Not trying to nail it's value, just the range since its (showato? Gunto?). Sorry, still trying to learn this sword language.
Thanks again.
