Beautiful "sangi" knife from the T'boli, I think the T'boli will call this knives different, sangi is what we use here for this type of knives, I think it's a Bagobo term. Blade seems to be very nice laminated, I would polish and etch the blade.
I reference again to my small collection:

When you bored to look at them send your both nice examples to me, they will be happy to meet their family members!
