That article nailed it. I even have the brown sword bag and mine is an exact copy of that except mine doesn't have a hole in the handle which really drove me crazy when trying to figure out what it was. I thought maybe it was made at the very end of the war and that was why it was so simple but it didn't match any of the other swords made then. I found a record on a Chinese website where one of these swords was auctioned over 5 years ago and they called it a naval sword and priced it at $750-$1,000. I've learned it is not worth quite that much which is fine, I'm just glad it isn't a Chinese replica. The toyokawa stamp is my favorite part of this entire sword and it is in surprisingly good condition which discouraged me early on. It may not be as nice as the swords carried in ww2 but it's still a part of the history of Japanese swords, a low part unfortunately. I will have to sell it but now I can rest assured I know what I'm selling.
 
	 
 
	It is incredible how recently the mystery of where these came from was solved. I'm really lucky I didn't get this sword 5+ years ago or the not knowing would have me up at night or I would've continued thinking it a replica. Ty to everyone who shared their expertise. I am very grateful.
