YEP KALANMANTAN STYLE YOU ALSO SEE MANDAU, SHIELDS AND SPEARS FROM THE SAME AREA DECORATED UP LIKE THIS. MY BEST GUESS ON THE TEETH IS PERHAPS THE FRONT LOWER TEETH OF A COW OR WATER BUFFALOW. NOT DOG TEETH ON ANY OF MY EXAMPLES. BUT AS MENTIONED THE BLADES ARE NOT IN GOOD SHAPE ON MY TWO EXAMPLES AT LEAST. VERY BARBARIC LOOKING ITEMS WITH PAINT HAIR , BONES AND SUCH.
