After considering the comments...below is my opinion.
> Rasdan : IMHO these hilts are of recent manufacture
I think so too. But mine is at least 15 years only. (That's how long I've kept it).
What I believe.
Mine is a 2-piece keris (although the hilt cannot be removed). It's not a keris sajen.
The piece is used as a protective talisman, in Malay/Indonesia, by a spiritual healer. To use against disturbance from malevolent spirits and such.
To add functionality, the inscription was added at a later stage.
- Why this particular hilt is used? I don't know.
But i guess, it's just a symbol that the keris is for talismanic use...
> rahman: what exactly does it say? Is it in Malay?
No, it's not in malay. See the images that I had posted. It's more symbolic rather than an incantation.
I appreciate the comments from all who had participated. Thank you.
