In the close up of the handle the little black dots visible, especially towards the end of the hilt, look like Haversian canals in cross section. This suggests that the handle is made from bone rather than a form of ivory.
Walrus ivory is extremely rare in the Philippines and would, I think, be restricted to high end, expensive weapons. I have not seen a convincing example of walrus ivory on a moro weapon. However, I have seen what was said to be dugong ivory on the pommel of a datu quality kris.
