according to my grandfather, this sword has been passed down through the family for well over 400 years. it's a wakizashi. my family says that back in the early 40's, the u.s. army searched their home and confiscated the longer sword, leaving only the wakizashi. i've been trying to figure out who it's made by but all of my Japanese friends say that the kanji used is really old school and hard to read. i'm hoping someone here can help.
