IT LOOKS LIKE A ADZ, A WOOD WORKING TOOL FROM NEW GUINEA, THEY ALSO USE BONE DAGGERS THERE. I SUSPECT THAT IS WHERE IT COMES FROM RATHER THAN BORNEO. BORNEO PROBABLY USED SIMULAR ADZ LONG AGO BUT DIDN'T USE BONE DAGGERS AS FAR AS I KNOW. THE BONE DAGGER MAY BE WORTH SAVING SO I WOULD KEEP IT RATHER THAN THROW IT AWAY.THEY STILL MAKE BOTH ITEMS IN NEW GUINEA TODAY BUT PROBABLY TRADE FOR METAL TOOLS FOR ACTUAL USE. THERE ARE SOME NEAT DECORATIVE ONES MADE IN MT. HAGEN THAT ARE CEREMONIAL IN USE AND NICE FOR COLLECTING.
WELCOME TO THE FORUM WE HAVE A LOT OF FUN AND LEARN A LOT HERE.
