Would any of you happen to know what this sword is and where in the world it might've came from? My knowledge is pretty limited to East Asian weaponry, so I really have no idea what it could be. It has an nice engraved sheathe and an "S"- shaped guard. My guess is that it's from somewhere in Central, South, or Southeast Asia, but I could be completely wrong.
Much thanks to those who help me solve this mystery! :)
