Philippines bolo knifes?

[Will1300]

Hello all.
I recently came across these 2 knifes which i presume is of Philippines origin.
They have some age from what I can make, the thicker one being the oldest I would say.
Perhaps someone can confirm and maybe knows more and can explain since im not big on Ethnographic weapons.
More pictures can be taken.
Both have a smith mark, on the small one its a P and on the big one its more of a symbol which I cant make out.

Much appreciated
