Hi all,
I'm not sure how it is treated, but i guess with the ordinary sour coconut water. I'm afraid the pctures are the only info i have at the moment. I'll try searching in aome other literature.
As for the origin etc, i metioned earlier that i lack knowledge of this weapon and my statement above is more a question than a theory. I have no idea if the theory has been discussed previously..hmm.. I probably had missed it.
Btw, I think i'll give a test after this to determine if it is tempered or not. Thanks for the opinion and advice guys..
Regards,
Rasdan
