Pak Ganja,
Got the nick from my late grandfather who used to liken my temperement to that of Arya Penangsang
.
Regarding the sepokal, like Alam Shah had said, I am not too sure whether that is a true blue Bugis or a keris from other regions, looks like a sepokal though.
I saw Raja Gunadala at the base of your keris (looks like a human figure?), I suggest that you keep it. Very nice old blade, and I would like to see it the bugis hulu and sarung before commenting any further.
