Hi David, 
I'm thinking it's positively Philippine from the handle, scabbard and general construction - a member of the Ginunting/Binangon family (unless someone cares to correct me).  I've been looking for one of these since I started Pekiti-Tirsia (FMA) almost a year ago - it's the "official" sword of that art.  I don't think it's laminated - the edge looks a little different, but I've found that this can be just a trick of the light on differently polished surfaces.  I might etch it just to see though.  If anything, it may have an inserted edge.   I would agree that the scabbard is a newer replacement. 
Tom
