Hello Roland,
never seen a badik like this, very unusual. I have a badik from Salayar island but with a starlike cross section, see here:

The scabbard/fittings again very similar to one from my collection which I think is from Sulawasi. When you want I can post pictures from it.
Nice and unusual catch, congrats.
Regards,
Detlef
