Shahrial,
I also thought both the cross-piece and the hilt looked "Batman".
But I didn't want to confuse the references because Kai Wee called it kerbau.
Seems as if we both liked Batman as kids.
But my favourite was the Phantom.
Kai Wee,
Thanks for your explanations and reference pictures.
Look forward to read some more when you have checked with your Indonesian source.
