ONE POSSIBILITY IS THAT THEY ARE A VARIATION OF THE CHINESE SWORDS USED FOR TEMPLE OFFERINGS. IT WOULD BE EASY TO TELL IF YOU HAD THE ITEMS IN HAND BUT PICTURES SUCH AS THESE JUST CAN'T GIVE ENOUGH INFO. IF THE POMMEL FINALS ARE THREADED AND JUST A FANCY WINGNUT AND THE BLADES OF POOR QUALITY I WOULD SAY TEMPLE OFFERINGS. THEY ARE OFTEN FANCY LOOKING BUT OF POOR WORKMANSHIP AND NOT FOR USE AS A WEAPON. THEY OFTEN GET SOLD TO TOURISTS AS SOUVINEERS ALSO.
UNFORTUNATELY I DON'T KNOW ANYTHING ABOUT THE CEREMONYS OR WHY THEY ARE OFFERED TO THE TEMPLES BUT HAVE HEARD THE STORYS LOTS OF TIMES OVER THE YEARS. I HAVE SEEN MANY OF THEM AND THESE ARE A BIT DIFFERENT SO MIGHT BE A VARIATION MADE IN JUST A CERTIAN AREA, BORNEO PERHAPS FOR THE CHINESE THERE.
