Thanks to everyone for their nice comments.
Nathaniel, the spear-like weapon you are referring to appears to be some sort of an Indian polearm. I have never encountered anything quite like it in literature or with dealers. I know that it is likely of Indian provenance because of a crisp Bikaneer armory mark visible on the blade. The longer tip is similar to a tulwar blade - it is sharp on the outside and has a obvious false edge on the inside. Must be great for both slashing and stabbing. The shorter "blade" terminates in an ace of clubs like finalle. The haft was possibly cut down a long time ago but I can not verify nor deny this. For all I know it may have been this short all along. After much research and deliberation, I came to a conclusion that it is a combination ploeram/swordcatcher: If an oponent's sword is caught in the "fork", a small twist of the wrist will easily lock it in place. I can't really think of another reason to have such a strange head. It's either that, or it is a giant can opener
If my schedule allows, I plan on doing a small photoshoot this weekend and will post some close ups of this and a few other pieces from the collection for further discussion.
