Help with a couple old metallic arrow points

[wildwolberine]

I purchased these two arrow points together. I believe the leaf shaped steel point is Cordilleran Peoples/Igorot, from Luzon. There’s some fine carving on the shaft behind the plant fiber bindings.

The other, barbed point is a mystery. It’s made from non-magnetic metal, perhaps brass? It’s quite thick and heavy.

I wonder if they were collected together in the Philippines, or if the barbed tip was collected in South America or elsewhere?

The shaft on this point is cane or a cane-like material. I feel the twine binding covered with a waxy substance is common in South American arrows.
