Thank you both!
Charles, if you are referring to the trident made of silver inlay, Cato says that this is a protective symbol for the owner/wielder of the kris facing the enemy. If this is true, I also wonder if was a carry over from Indic influences long ago (Majapahit Empire) or from trade with India and Indonesia. The roots would be from perhaps Shiva's trident and thus talismanic.
Detlef, your will see yours.........
