I would like to thank everyone for their replies....obviously I'm not the only one for whom this has stirred an emotional response. I haven't replied back until now as I'm still somewhat stunned as I went from knowing virtually nothing about it to all of this in just a few days. I'm still a little confused on how old the nihonto itself may be in light of the "ichi" character.
I certainly agree it should be 'preserved' as a historical record and I will give careful consideration as to just what that entails. My initial reaction is to preserve "as is" and keep from further degradation. As much as I would like to see it in it's artful form, I believe it's story is best portrayed in it's present state. To me, the time-worn condition best symbolizes how antiquated the times in which those actions took place have become....that the human race has indeed positively evolved somewhat and left such attrocities behind.
That's what I would 'like' to believe.
I can't help but think that bringing it back to a beautiful state of being would somehow "idolize" it; thus, twisting the message of the inscription for some.
On the other hand, the argument could be made that by restoring it to it's former beauty, it's ominous lethality would give more credibility to the inscription for others.
Maybe that's why my Grandfather brought back 2 in such opposing condition.........
