Related mysticism (Java)

[Atlantia]

Well, good afternoon gentlemen.

As you know I usually confine my half baked opinions and ideas to the two other areas, so you can imagine I am stepping out of my comfort zone in being here!

I was chatting to my Mrs about various traditions concerning weapons and happened to touch on the Keris/Kris.
During this conversation I was telling her about a documentary that I saw many, many years ago about Java.
In it the crew visited a Kris maker who used to make blades and (allegedly) push his thumb or lips onto the surface of the metal while red hot and leave an imprint.

I can't remember if they filmed him doing this, but they did show some very clear shots of the finished items with him holding them and showing his thumb/lips alongside the imprints.
It was very impressive!

Has anyone every come across this?

Also, either in that documentary or a related one in that series of documentaries, one of the crew became ill with an eye infection and they had to visit a local doctor.
I remember he had an office in a major city and cured people by electric shocks generated from his hands.
The crew were naturally skeptical and checked him over. He gave them various examples of his skill (scaring them a little) and then led them outside where he made a balled up piece of newspaper ignite by waving his hand over it.

Well, I have searched and cannot find the kris maker, but I did find the Doctor/Chi master!
