AH YES THE ROYAL RUG BEATER.
THE BLADE SHAPE REMINDS ME OF SOME TIKAR SWORDS I HAVE SEEN BUT THE EXTENDED GRIP IS VERY DIFFERENT MORE LIKE THAT ON A POTO SWORD. THE EXAGERATED BACK SPIKES ON THE BLADE ARE INTERESTING AND ONE APPEARS TO BE WRAPPED WITH WIRE OR SOMETHING.
WHATEVER IT IS IT IS WAY COOL AND I LIKE IT.
I WOULD GUESS CEREMONIAL USE BUT AS YOU HAVE THREE EXAMPLES NOT A ONE OF A KIND ITEM AS I FIRST SUSPECTED.
