I HAVE SEEN THIS SORT OF KNIFE IN INDONESIA AND MALAYSIA AND IT WAS USUALLY MADE BY LOCALS WITH COPPER OR BRASS AND OCCASIONALY BRONZE BLADES. THE ONES I HAVE SEEN WERE ALWAYS SMALL AND HAD WAVEY BLADES AS WELL. YOUR EXAMPLE IS A LOT BETTER MADE AND MUCH FANCIER THAN THOSE I HAVE SEEN BEFORE.
THE GRIP LOOKS TO HAVE BEEN MADE FROM THE LONG PASTERN BONE FROM EITHER A CARABO ( WATER BUFFALO) OR HORSE. SEE PICTURES OF COW AND HORSE LEG BONES, THE LARGER PICTURE IS HORSE LEG. THERE IS A OLD FORUM POST ON THE SPIRITUAL AND MAGICAL POWERS ASSOCIATED WITH THIS SORT OF KNIFE.
ITS THE BEST I HAVE SEEN OF ITS TYPE.
