Actually, my totally un-scientific but gut reason for thinking this is "genuine" (in the sense of having been made or cobbled together for actual use, rather than created as a copy) is the fact that it looks so weird. I would expect a copy/replica/forgery to look more like something ... well, real.
The big hole in my flawless logic is that it could be something someone made a year ago for the hell of it, either completely or from an older blade (broken or otherwise).
But, at the risk of my male poultry, I am sticking to my attribution as a roughly-done re-hilting of a broken kilij-like sword. 100%. Of course, being only somewhat knowledgeable about one particular type of Asian swords, I am perfectly safe in expressing outrageous opinions about completely unrelated swords, because no one would seriously think I know what I am talking about, so I have no credibility to lose!
