Manolo, after watching (Empu Djeno) keris-making video,

I'm convinced that it's not possible to get a good quality keris from CAM process. Knife shapes are simpler to make whilst the keris, due to it's luk shapes, curves, ricikan and grooves are difficult and almost impossible to emulate by modern process.
Experiments are always welcomed (at your own risk and cost).
So Tim, no worries. By the way can I see some examples of your work, please.
