Kuwa-jutsu developed in the same way as Kama-jutsu. Both are edged weapons in Okinawa classical martial arts. Kuwa was the weapon used mostly by farmers, and it has a sharp edge and handle for defense and attack. Kicking up mud at an attacker is one of its unique moves. Kuwa-jutsu was studied by martial artists and upgraded with the influence of Chinese martial arts before becoming an actual warfare weapon. In Okinawa Kuwa-jutsu is practiced exclusively by Matayoshi Kobudo practitioners. Outside Okinawa; in Fuzhou and Shanghai, there are martial artists who are still able to use this jutsu.
