The sword of the day is the tonfa.
The tonfa is a club originally used by the people of Okinawa, in Japan. Like many weapons, it originated as a tool, or rather part of a tool. The traditional origin story is that it was developed from the handle of a millstone, used for self-defense after other weapons had been confiscated by samurai. There is some debate regarding the weapon’s origin, though, and although it is most heavily associated with Okinawan martial arts, variants can be found in China and Southeast Asia as well.
they originated as part of a leather vambrace and they're from Mesopotamia, being brought to India later and along with many traditional Indian weapons, was incorporated into the Wu Shu style, a foundational martial art of almost all Chinese martial arts of the day.
Later being replaced by metal rings, they became relegated to the peasantry as tools for sporting competitions being rather popular in the fringe states at the time, Thailand, The Philippines, Vietnam, Cambodia, etc.
Later, the same fighting style was applied to the millstone handles, since they were functionally the same in design. This is when the grip handle component was added.
