Sword identification

So I found this short sword when I was cleaning out my Grandfathers house. I would love if someone could help me identity what I have here. It looks a few hundred years old. It’s not in the greatest shape. I am sorry If I am not using the correct terminology. My expertise is with firearms. Thanks for looking.

Can't help much with it other than saying...DANG that's cool! Great find (I think).
