Hi Blu Erf,
the second Panjang is really beautiful. On the first Panjang pamor on sorsoran looks like a Bintulu - mouth and one eye

, or in this case better o)
Probably there must be simply more material on sorsoran becouse of thickness of blade there. Additional material could be welded on (?), if it is not something like V from beginning - the first one looks like this.
