Bolo/parang knife of unknown origin

[wildwolberine]

This arrived today. Wondering if anyone could ID origin? I imagine it’s Filipino. It’s a utilitarian piece showing considerable use, damage etc. It’s definitely chisel ground. There are aspects that remind me of the Zamboanga knife I posted here (http://www.vikingsword.com/vb/showth...ight=Zamboanga), specifically the notch holding the twine wrap.
