I can't find a good picture of it online, but on Ross's apartment in the first few seasons of Friends (before he moves into Naked Guy's apartment), there's a wall hanging he has near the door that looks like some kind of spear, possibly asian. I thought it might be a yari, but it looks to be about 4' total length, with about half of it blade and half of it handle, which doesn't quite look like a yari.
Anyone know what this weapon is?
