The origins of the tonfas
"The Immortal Weapon"
There are numerous explanations for how the Tunkuwa, Tonfa or Guai (拐) first appeared into the world of martial arts. Whatever its origins, it has undoubtedly been developed as a weapon and for martial use and has gone on to reach worldwide popularity as the police PR24 side arm.
The prevailing Okinawan history is that the Tunkuwa (Ryukyu pronunciation) was used within households to turn a grindstone and that for this reason it is a weapon associated with kitchens and with women. However the Chinese explanations are quite different. One of the most romantic histories is associated with the Daoist immortal Li Tieguai (李鐵拐) which can be translated to mean "Iron Crutch Li".
Li Tieguai was by some accounts a contemporary of Lau Tzu the father of Daoism. Li famously walks with a crutch and is one of the great eight immortals. He defends the weak and the infirm and protects all who face disability. His iron crutch is unable to be destroyed and is his primary weapon for fighting, if he is ever to do so.
The manner and shape of the traditional Chinese crutch is very similar to the modern weapon except that it is much shorter. A different legend tells of how an unnamed martial artist who was fighting with a crutch against a sword suffered from his crutch being cut in two. The martial artist then held the two pieces of the crutch in either hand and so the “Seung Guai” or “double crutch” weapon was born.
