For those who have seen and handled many Type 94, 98 etc swords, how likely is it that they tsukamaki is original to the sword?
In the grand scheme of things the 1930s and 1940s were still within living memory, so I suppose that more than a few of these swords escaped the conflict and possible ill-treatment to survive until today in decent shape, however I've seen quite a few that have wrapping that looks almost too clean. Granted the blade are also usually in good shape as well, so either someone put in a lot of effort on an old military sword or the original owner was stationed back on the mainland away from the action.
