Bali Keris with 10 luks...?

[Athanase]

Hello everybody.

I recently bought this old (before WW2 I think) Bali Keris because I like the warangka. The seller told me that he had bought the contents of an attic with many objects from 1930's (and some weapons of various origins).
I have observed the kris before buying it, but I made a big mistake. I did not notice that the blade had an even number of waves (10).
The blade measures 35cm (37cm perhaps originally). I guess the blade had to be very rusty and is at last cleaned the 11th wave broke too damaged.

So it asks me a question:
When Indonesian restores a an old knife in very poor condition whose last wave was rusting out or broken.
- They keep a kris with an even number of wave?
- Or they remove a wave to keep an odd number?
