I agree with Ian that this is a Maguindanao blade and and from the early 20th century.  I can tell that it is pattern welded.   
 
The metal mounts seem to be made of woven silver and brass or low copper/silver alloy bands.   
 
As far as the pommel is concerned, it looks like horn, though there is a possibility of kamagong.  The inlays are definitely bone.  This is still a datu class piece.
