Steve:
We've been talking about this one on another thread, as well as a couple of earlier examples --
Interesting Lumad sword. Despite the apparent age (patina) on the blade, I think this one is all recently made. The blade style is not a recognized Moro pattern, and a contact of mine in Manila has identified the sword as coming from the Tagakaolo (Kaolo, Kaolu) people who live around Mt. Apo, just outside Davao City.
Good quality workmanship in this piece, but not a $400 sword IMHO. I paid about half that amount for another one on eBay a couple of months ago.
