A mix of styles between a large keris and the Malay/Moro kris. The wide long luk suggest the Malay/Moro style, which goes with the scabbard. Perhaps a transitional piece, in which case it must have considerable age because the Malay/Moro kris was reported by early Spanish colonists in the Philippines.
