Hi all! My family has recently been gifted a wakizashi. I'm told it was an item surrendered between generals in WWII. Obviously not a WWII-era item, though. From what I can tell, the blade came from a maker in Izu, but the name is beyond my ability. There are additional signatures on the tsuba and fuchi - the kanji are much more legible, but I don't know enough to come up with a reading. Any help would be greatly appreciated by my family! Picture here, link with more.
