I’ve got a [url=http://www.mot.be/cgi-bin/collections.cgi?c=ID-DOC&i=698&l=fr]three-pronged weeding hoe* hanging on my wall right now, that I’m in the process of giving a fake leather handle, a layer of wood stain, and some inscribed runes.
You might also try looking up a book called, simply, Weapons, by the Diagram Group. (A good library or bookstore should have it) All sorts of weapons, of all types, including many you may never have heard of, are illustrated in that one. A good read.
