Hai Bill,
What you've got are a special kind of tombak what so called as 'menur(?)'. I'm not quite sure about the name. The menur usually mounted on the top of umbrellas (not that ordinary umbrellas, but the one which used by Javanese noblemen) or on the center of the shield. Javanese shield usually covered with many spikes, but the bigger ones with pamor, the menur, placed on the center.
The bedor is smaller than menur. It was really used on the war, but not to shot every enemies you encounter, certainly. You used the 'holy bedor' only at whom you consider as your 'invincible/invulnerable' enemy.
The blade Javanese put on the 'walking stick' (called teken or tlempak) are ordinary tombak, but they choose the smaller one.
Another very rare weapon is 'candrasa'. It was used as 'kancing gelung' or hairpin, something to keep your hair spun tight. (in the old days, almost every men had long hair). When enemy comes, candrasa used by throwing it toward the enemy.
As you see, the javanese ancestor was very resourceful
