Hello Sirek and David, 
This is indeed a very good suggestion and i think it might be the correct one. At least it's much more probable than 
my Sumba theory (this post is currently still under moderation so you didn't see it). 
 
I had a closer look at some more of those sirih pestle hilt  
and many of them have  carvings similar to my hilt. 
Most of them look very much like keris hilts and the pestles have probably a tang that is not much thicker than a keris pesi which makes them a suitable and  
inexpensive replacement. 
 
Best Regards, 
Thilo
