Origin of the Jawa Demam hilt form

[Sajen]

I think this will be very difficult to find out from where it come from. But maybe, and this is only a guess from me, it's origin is Cirebon.
You remember this threat:

But maybe it will be nice when we can see in this threat many different Jawa Demam hilts. I also have some.
