Hello Jose, here is another sword with a non-typical kris style blade. This one is from the town of Taal in Batangas. What I am getting at is that I believe that both this sword and the one that Carlos has are based on traditional (if be it rarer forms of) kris swords. The one pictured below is easy to identify where it is from seeing as it is inlaid into the hilt but the origin of the one Carlos has is a bit more of a problem.
Best,
Robert
