Folks -   So this listing of a sword caught my attention.  It is not my sale nor my interest to bid on it, but I am teaching my son about collecting militaria and I have shared that when folks throw around the term "rare"  -  be cautious!     I noticed right away the mix of modern and dated koshirae, if I state that correctly.  Late war saya, etc.      From studying my references and listening to you good folks, I know right off the start that a photo of the full tang is most helpful.
