Could anyone show me the butt end of a Bontoc spear ?
The reason why I'm asking this, is because I got a spear offered to me which appears to be Bontoc (as far as I can judge). It has a harpoon shaped spear head. The wooden shaft is a bit 'swollen' at the spot where the spear blade enters the wood. There's also a heavy metal band to prevent the wood from splitting. It has a short spike at the other end.
Sorry, I don't have any pictures (the spear isn't mine, yet

)
I'm still hesitating to buy it, that's the reason of my question. I have little knowledge of Philippino weapons.
