Can someone help me identify this tiki-looking dagger?

I'm clueless as to what this dagger might represent. I took 1 picture of it before my camera battery died, and now a co-worker has the camera so I won't be able to get more pics until later.

The handle and sheath feel like either leather or a really soft wood. There appears to be a human tooth set into the sheath, as well as maybe a bear tooth in the handle?

This thing freaks me out big time, though.

Any thoughts?

That'd be an awful small bear I'd think. It could be a dogs tooth.

And this is a bump as I am interested as well.

probably Aztec or central America in design.

Aloha, I've seen a display sword with similar adornments. I have a Tiki insense burner made of bamboo and built up with
clay. It also has colored smooth stones affixed.

Heres another style listed on Ebay

These are made in Indonesia and the teeth are horse teeth.
