How thick is the blade, Albert?
A very good, bent kampilan...
IMHO it doesn't help trying to relate these unusual pieces to some of the more well-known styles. We know there have been quite a few more different types around even if they are nowadays tough/impossible to pin down (including exact origin and names).
I'm not yet fully convinced this really is a Moro sword. The hilt might also have some Melayu and/or coastal Borneo vibes and I also have a tough time attributing the engraving of the bladebto any specific Moro group...
