WOW!!! That is truly a unique and rare kampilan. The pommel is truly nothing I've seen before. The carving is well executed! Not only do you have a unique pommel, but you have a scabbard and a crossguard with handguard/staples on BOTH sides...rare on both accounts. This is truly a unique find. The blade looks like it is in pretty good shape and, as Federico noticed, is probably hiding a nice pattern.
I was also wondering as well if the pommel is a recarve, but then there wouldn't be enough material there if the original pommel was your typical kampilan swallow's tail/croccodile jaw form. But as Federico mentions, if it was a re-carve, then the only form possible with enough material to re-carve from would be one of those ultra-rare kampilan hilt forms that Cato mentions in his book and is pictured there as well. I've never actually seen one of those forms, but the picture in the book where the Moro retainer has it resting on his shoulder shows how massive it is. If I remember right, these kampilans were more ceremonial than actually usable. If indeed this example is a recarve of one of those massive rare forms, it was probably done to lighten the weight of the pommel and to make it a more viable weapon.
In any case, the pommel is truly unique whether it's original or a recarve (it does kind of look like a parrot
.) That and the fact that it has double-handguards and a complete scabbard makes this quite a rare and unique kampilan. Excellent find!!!
