Well Quis, it seems that you are determined to get your keris restored in the Philippines, so I wish you the very best of luck.
As to luk count, yes, this is associated with belief systems, but those belief systems are Jawa-Hindu, Bali, and Islamic Javanese.
This link will take you to a page of a paper that I published a few years ago that puts forward some ideas on how luk were originally counted and how and why they are counted differently now.

Incidentally, coconut oil is a very poor base for fragrant keris oil, singer sewing machine oil or medicinal paraffin is far superior. Over time coconut oil will go rancid and generate a very unpleasant odour, if left on a blade for too long it will require serious solvents to remove it, and years to get rid of the stink.
