If you are looking for a self-defense tool, you can opt for a Tonfa. The Tonfa is a short striker, which is characterized by a transverse handle. Tonfa appeared for the first time on the Japanese island of Okinawa, where it was inextricably linked to millstones that crushed grain or rice. With the aid of Tonfa millstones could be moved. In Southeast Asia, for example, in Indonesia or Thailand, Tonfas were known as a weapon – as most of us know it today.
