I am looking for the proper name of the sword in the image below. I was not sure which stack exchange site to post this on so I put it here, figuring it was a type of medieval weaponry, if an obscure one.
It's probably something someone just made up. There is something similar, but I couldn't find a name for it. It was made in Liberia. Here's a hyperlink to the image from the Spencer Museum of Art.
Update: Commenter justCal referred to it as a kuba sword. Google search confirms.
