Hi, all that I have learnt of the Kris is relatively new to me from study and an elderly friend who spent a very long time in and out of Bali in the 70's and 80's with the people who inhabited a 10th century water temple far removed from the tourist Mecca we all know of today. From all that I have read and learnt first had from those who have travelled there is that it is entirely form before funtion with regards to these knives.
From all that I can gather from my talks with Max, the Kris and every part of it is all a spiritual connotation, much like the importance of the Gajah in their culture which it also found on Kris knives as are other "items" that are held with great importance like the Naga and many others I have seen on old blades.
I have always said to Max how much the Genang side of a Kris reminds me of the Indonesian Archipelago and I am only surmising that Genang being a city in this Island chain is represented on the blade, it may be how it all came about, or this ideal of mine may go back further and hence this is how the city received it's name. If anyone can touch on the origins of the city of Genang, here may be the answers....
Hold your Kris knives up against the map in the link below and tell me what you think? I beleive the line between Ganja and the main blade of the Kris represents the break between the major islands which would put Genang in the correct position on the blade.
