I am inclined to follow Empu Kumis' lead here. Even though i was willing to concede to an earlier 20thC date as this type of keris has been made in Madura since at least then, i believe E.K.'s expertise in this matter is certainly far greater than mine. I thank you for your detailed explanation as to why you date this keris as you do. This is just the type of information that is often lacking in people's assessments and is crucial to our understanding and learning of this very complex subject.
All other terms are clear to me, but i am still not quite clear on pudak sategal.
BTW, i understand E.K. holds keris to a very high standard. I still think this is a nice keris, it is just not a kraton piece.
