A VERY INTERESTING WEAPON, IN JAPAN THEY CALL IT A SAI AND THEY USUALLY HAVE A ROUND CENTRAL SPIKE NOT THREE SIDED LIKE YOUR EXAMPLE. THEY WERE USUALLY USED IN PAIRS AND WERE EFFECTIVE FOR PROTECTING AGAINST SWORDS AND COULD ALSO BE USED TO DISARM THE SWORDSMAN. THEY WERE USED BY THE POLICE IN EDO SOMETIMES TO DISARM AND CONTROL THE SAMURAI ALONG WITH THE HACHIWARA AND VARIOUS OTHER WEAPONS. WHAT IS THE HISTORY OF THE WEAPON IN CHINA ? AND HOW LONG IS YOUR EXAMPLE. THE REMAINS OF THE FACETED SHAPED POMMEL KNOB IS MOSTLY FOUND IN CHINESE DESIGN, A NICE EXAMPLE.
