Small knife for ID

[Ian]

This knife came in an inexpensive auction lot labeled "Two Mexican Knives." The other knife was a larger Filipino knife from Luzon, more specifically from Laguna Province, and was probably late 19th-early 20th C. That knife was the one that interested me and this smaller one was a throw in.

However, I am stuck on what this knife is and where it came from. It does not look like anything Filipino that I have seen before, nor particularly Mexican.

The blade is clearly old, heavily pitted, and much used. The recurved edge and drop point suggest a domestic tool rather than a weapon to me, somewhat similar to a hansia found in Nepal and adjacent areas. The handle is bone, the partial tang is secured by a single large pin, and there is a small metal ferrule. The bone is deeply carved with scroll work.

Thoughts and suggestions welcome.
