Filipines is a divided country more than just by water. There is a strong Christian and strong Muslim influence as well as local religions and traditions. Some of it depends upon where the art came from and who trained in what.
The Honor I have heard and seen from some (* My limited exposure*) of the Old Generation is :
1) You lost honor if you were disarmed.
2) Your wife or mother could run in and stop a fight (* No real fighting man would hit a woman *), from going past injury where serious injury or death may be involved.
3) Prayers and devices for luck or power. (* Anting *)
4) Using control to not kill a person or damage a person but to let them know they were hit or would have been hit.
5) When two people faced off, only those two would be involved.
. . .
And what I have also heard about is that it was used in the streets by thugs, and in many areas it was not respected by the upper class, and used by field hands and the uneducated. This is why Judo and Karate became very popular as they were seen to be legitmate and more approachable by the general population.
Some Figthers would not face each for the reprecussions of their families, it would set off a blood fued, or so and so also carried a .45 and was not afraid to use it or their friends were not afraid to use their own weapons.
Some people were connected or had influential families and if you disarmed them, this would allow them to save face from being hit and or having a bruise, and their father or uncle would not have to do something to defend the honor of his family, etcetera.
So, it really does depend upon the art and the instructor, from my investigations and understandings.
