“When the ringed dao is drawn, the rings hang down, and the center of gravity of the sword will be offset in the direction of the hand.
When slashing with force, the rings will move forward with inertia, and the center of gravity of the sword will shift toward the direction of the cutter head, thus increasing the slashing force and lethality.”
