Marbel, thanks for clarifying your opening post. As i noted, i am well aware that the Tboli people prized the Moro blades, but generally, once such blades were brought into the culture they were given a Tboli treatment in regards to dress. I am sure you have experienced this since you posted one of these not too long ago.

If you say this particular keris was in the possession of a Tboli datu i will certainly not doubt you. But i wonder under what circumstances since i would think if such a blade were to be actually used by a Tboli datu he would be likely to redress it to reflect his own culture.
