George, thank you for posting this puppy. Though not unheard of, it is seldom that you see twist core in Moro, especially
double twist core like yours.

Amazing. You see more of this in earlier pieces than later.
Regarding the panday training, I'm not sure that is had to be some one Chinese. I have a double twist core Bagobo piece and there are not many (if any) Chinese living in that area.
I also like the silver inlay.
