Moro Spearhead, but from what Battle?

[Rick]

The fastenings of the spear head have a 'last ditch' look to them.
I'd guess that the shaft was cut to facilitate either easier transport from the Philippines or for hand-to-hand combat.
I have seen Budiak with an iron loop at the butt end and I believe this was to facilitate retrieval of the spear by an attached cord.
