I bought a box with a few krissen, most of them in poor condition !
The reason for purchase was that, my eye had fallen on a type of warangka that I think is Banjarmasin? ( Including the special "restoration")
I saw this type in a earlier tread:
a nice wrangka with the exagerated lambe and decoration on both sides, and a beautiful wooden carved hilt (not the usual one with the many (non)-precious stones)
my opinion is that they are quite rare, there is little information available
Maybe someone can tell me more about it?
