I agree with the majority who places these knives from Asia.
I'd also point out that the Shuar (Jivaro I believe is a derogatory name) were Stone-Age at contact, and I suspect that to this day, they don't work metal.
Otherwise, yes, headhunting (as opposed to head shrinking) was widespread. We can start with the Celts, if we want. I know more about it from modern groups in Irian Jaya and Papua, but certainly the Toraja, the Mentawai, and various Dayak tribes were headhunters in Indonesia.
I've been Googling for Philippine headhunting tribes, and so far, I've found references (real or not) to the Ifugao, and to other tribes in the hills of northern Luzon. If I had to guess, I would start looking at the minority groups from the Philippines as the source for this blade. I haven't tripped over a cana (Cane?) tribe yet, but potentially it's out there.
What do the PI people think?
