You must have been a good boy.Santa is apparently being very nice to you this year. And so early. Bt this can only mean that yo will only receive a bag of coal on Christmas Day.

As for the Sumatran and the gold, i will say that i also have a Sumatran keris with gold and i was equally worried about washing and staining it. I held my breath and did it anyway and was quite pleased with my results. I can't guarantee
your results, but it can be done. Mine is also missing a little bit of the kinatah, but i'm not sure there is anyone who cold restore it for me or if it wold be the best thing to do so.
