Report Grandfather's Find, My Curiosity in General Nihonto Related Discussion Posted October 6, 2012 Thanks for the word, Geraint. I truly hope there is something to be done - even if it is just removing the rust and seeing the way it was made. I have no intention of ever using it for JSA, so it wouldn't need to be pristine, but anything to help me figure out the age, you know? Even more than swords, I am a lover of history. And knowing this things general age - if that is even possible - would be more valuable to me then having it restored.
