In January 1946, a man who identified himself as Sgt. Coldy Bimore (likely a garbled phonetic spelling) claimed the sword on behalf of the U.S. military, and it's not been seen since. While sleuths have tracked down a Cole D.B. Moore as the probable culprit, the man's family doesn't have the sword, and no one has any idea who he might have given it to.
The most common theory is that someone in the military, not realizing that the Honjo Masamune was far more valuable than all the other cutlery being turned in, took it home as a trophy, and god only knows what happened to it from there. A priceless relic is likely sitting in some Midwest basement or pawnshop, if it hasn't been snatched up by a Soul Calibur cosplayer. So if you or anyone you know has a sword hanging in their bedroom because they hate having sex, give it a close look to see if you can solve a mystery that was literally lost in translation.
