Bali Keris found it's way to me

[milandro]

very well, the process can be reversed , so, even if it goes " wrong" ( as in too dark for example) you can re do this

there are probably many ways to do this , including polish with wet and dry sandpaper as suggested , prior to staining which is something that people who use Warangal in the NL don't do (to my knowledge) while it would probably be more consistent with the original way this was made on Bali or Lombok
