Sword Identification

About a month ago, doing demo work on an abandoned house, I can across this poor soul in between a wall we were knocking down! As you can see from the pictures, this soul has been abused, beaten, chipped, dented and filed. It is stained and sad! The Katana has always been the favorite sword since I was a kid. Seeing this soul in such sad disarray, hurt my heart and soul! The Katana was an extension of a Samurai soul and in my own way, I could feel that!
