Dual Tonfas

The tonfa is basically a stick with a handle sticking out near one of the ends. This weapon is Boring but Practical made manifest. However, boring isn't good enough for fiction, and naturally all sorts of variations (including the the bladed tonfa, the energybeam tonfa, and the tonfa that doubles as a gun among others) have been dreamed up by writers in order to spruce up the humble handled club.

Wielded in pairs with one in each hand, a martial art based on the use of dual tonfas (Kobudo) exists in the Japanese islands of Okinawa. Archaeological evidence suggests the first tonfa were of Chinese or Indonesian origin, but they enjoyed much more widespread use in Okinawa and other Japanese islands. There it was claimed to have been developed from a a modified millstone handle as a result of the restriction of conventional weapons by the rulers of the land back in the day, forcing people to make their own weapons, often out of farm tools.

They are a staple in weapon based fighters, where they are most commonly the main weapon for one of the female characters, and in any anime or manga where all kinds of weapons are already around they will often turn up somewhere down the line in the hands of a character, usually either a competent part of the hero's team or a major threat to the protagonists.

In real life, the common policeman's Nightstick is based upon this weapon, and in the end is just a modified version. It is preferred over regular batons because it is better for defense and looks less threatening. The main difference between them is that police use just one nightstick whereas with tonfas Dual Wielding is the norm.
