As an aside, there is a curious similarity between the tikko and the bankokuchoki of the Nagao-ryu. According the the late Don Draeger, the bankokuchoki was a metal ring grasped by the hand and used to deliver strikes (Draeger). The Nagao-ryu specialized in Kakushi buki (concealed weapons) and was popular with the common class during the Edo period. Whether the tikko could be used in a similar manner to the bankokuchoki is unlikely given the focus of the kata techniques (Maezato no Tikko) which seems more focused on defending against an unarmed attacker. Regardless, below you can see an example of bankokuchoki against sword.
In the Ryukyu Kobudo Shinko Kai, founded by Minowa Katsuhiko, there are two kata practiced for the use of hand held weapons. They are Maezato no tikko and Minowa no ticchu. Maezato no tikko was formulated by the late founder of the Ryukyu Kobudo Hozon Shinko Kai, Taira Shinken and was named after his original family name, Maezato (2) (Nakamoto, 1984; McCarthy, 1998). Maezato no tikko is based upon techniques which he had learned from his grandfather, Kanegawa Gibu and from the Shorin-ryu Karate-do Kata Jion (Nakamoto, 1984). However, there appears to be some discrepancy as to the Karate-do Kata which was used as the basis for Maezato no tikko. Although Nakamoto has stated the Kata Jion was used as the basis for some of the techniques and the enbusen (line of performance of the Kata), other martial arts historians have argued that the Karate-do Kata Jiin is more likely the basis for Maezato no tikko (Sells, 1998).

The second, and to a much greater extent, less known hand held weapon practiced within the Ryukyu Kobudo Shinkok Kai is Minowa no ticchu. Minowa no ticchu was created by one of Taira Shinken’s student, Minowa Katsuhiko and is named after him. The Kata itself is based upon his years of study under Taira Shinken, his background in Uechi-ryu Karate-do, and his own unique interpretation of the weapon.
