Hi
David, Sajen, Alan and Rick, thank you for your opinions.
I try summarize it below:
1. Change the mendak (must be).
2. Keep the warangka & Pendok (need to be clean & re polish

).
3. Change the hilt with surakarta planar with much darker color wood , I prefer Kayu tayuman or arang and keep donoriko style hilt (stand alone).
I will post pics of the hilt closely and the final result of the keris make over as soon as i get back to Indonesia (probably on Dec).
would you mind to give your opinion on my others keris please ?
its 4 of them not 2 or 3 as mentioned it before....my mistake sorry.
