Grandpa's Keris

[Emanuel]

Hello Daniel, welcome to the forum.
This does look like a Bali keris, I can't really tell the dapur (shape)besides that it has 7 luk and a nice prabot (chiselled details) which looks very nice and well done. I've been wanting to get one for a long time, I think they're magnificent.
It would be nice to get a high-contrast pamor out of this keris, but the cleaning is quite an involved process, and unless you're ready to dabble with chemistry and use some arsenic-based warangan solution, it'd be nice to find someone who can do it for you. I've tried contacting some chemistry professors at my university for assistance, but no luck yet.
The hilt figure is a Raksasa demon I believe, and it sort of looks like many of the new ones on ebay. The scabbard also looks much too busily decorated to me, but that's just an opinion based on very little contact with keris.
You'll get lots of much better info soon from those who know

Regards,
Emanuel
