Dagger ID Confirmation Needed

[Robert]

This is another dagger that I've had for awhile. When I first found this dagger the previous owner had been using it to stir paint with. That is why it is a bit on the over cleaned side. It is 14-1/4 inches in total length with a 9-3/4 inch blade. The blade at its widest point is 1 inch and 1/4 at the thickest point. Brass fittings with a horn grip. I believe that this could be from the Philippines but would appreciate everyones comments and opinions on its origin of manufacture and possible age as I've never seen one quite like this before. Sorry about the picture quality but because of having to be taken indoors I had to use a flash. Thank you.
