A very ancient weapon which has been used all over the world, in ancient Greece, the celts, in India, japan, South east Asia is a short stick with a double point. It became a religious symbol and monks used them to defend themselves when they could not carry other weapons. Its called yawara in Japan and dulo dulo in the Philippines but what do they call them in Indonesia? Probably my favourite weapon as I think it more usable in todays world i.e. could be replaced with a steel pen, torch etc

I know this doesn't constitute "exhaustive research." But a quick scan of the Wikipedia entry on silat weaponry doesn't list anything like the palm stick. Closest I saw was the toyok or tembong (stick). But the description sounded more like something akin to a baston or olisi ("eskrima stick").
I believe there's a Korean term for it as well (dan bong?). Sadly, none of those really address the OP.
