Concerning the "interest":
I "tried" to buy this blade some months ago as a gimei blade.
If I would have been successful, I would have had a try for new papers - but seriously I wouldn't have had hope to get them.
If it had failed, I would have kept the blade as a healthy nice wakizashi as a gimei example or would have removed the mei and would have had another try.
It happened in the past, that after removing the (gi)mei the blade was attributed to the smith the blade was signed before...
Would have been an interesting project
Why didn't it work?
Because the previous owner didn't accept my offer (about 4000 USD - very generous for an expected gimei I think ;))
Since I have now answered this question, although the answer was obvious before, I want to see my commentary as what it is... just some thoughts on the sellers post
