I am sure that many if not all of these blade (i say blades but we don't really see them in these pictures and videos, just the dress) are fully functional and have utilitarian purpose. Most are probably recent blades, but some could be remounted old blades for all we know. After all, we don't really see them. But i think the bottom line really is that the barong and the kris are both deeply symbolic weapons to the Moros and carrying these smaller examples is no doubt meant to express this symbolic relationship. Obviously with automatic weapons and rocket launches on their shoulders these blades are no longer meant to be their main weapons as they once were. At smaller size they maintain the tradition and history of the Moro warrior and are probably pretty effective as brush cutters and utility knives.
