Thoughts on this crude spear?

[wildwolberine]

Here’s a crude but sharp spear tip, it does remind me of Igorot spears from Luzon to an extent but those are much better finished. I imagine this is SE Asian? Not flexible, the first part is sharpened with the rest dull/not beveled, short tang. Looks to have been re-sharpened, has a practical feel to it, could be made for sale but awfully sharp. May be unclassifiable?
