Kakie is a traditional form of Okinawan training similar to sticking hand practice from the Chinese Martial Arts such as Tai Chi and Kung Fu. It is also a fundamental part of Tegumi or Okinawan wrestling.
The traditional method of training Kakie conditions the arms as well as teaching sensitivity, depending on whether the contact is heavy or light. With light contact you can sense the intent of your partner before he actually moves so you are immediately ready to counter his movement. A variation of the drill is to use one hand against your partner’s two hands and to practise with your eyes closed.
