Sai is the second weapon
that students are taught
in Matayoshi Kobudo Kodokan.
This is one of the few weapons in Matayoshi Kobudo that came to Okinawa as
a weapon rather than as an agricultural or fisherman tool as many of the Matayoshi
Kobudo weapons were initially developed. As the Bo, this weapon training involves
the practice of kihon, kata, kumi and bunkai. The length of the Sai is determined
by the length of the forearm of the practitioner. The main purpose is to have
a Sai with such a length that if the practitioner is holding the Sai in his
hand the tip of the Sai will be just a little bit longer than the elbow.
Matayoshi Kobudo Kodokan practitioners will be introduced to Tunkua as their
third weapon. Even though at the Kodokan the name Tunkua is used, this weapon
is also known by other names such as Tonfa, or Tuifa. This weapon originated
from an ordinary household utensil, a handle for a mortar or a hand mill.
As the Bo and the Sai, this weapon training also involves the practice of
kihon, kata, kumi and bunkai. The way to determine the length of the Tunkua
is very similar to the Sai which means that it is determined by the length
of the forearm of the practitioner. As the practitioner holds the Tunkua by
the handle it should be placed against the forearm; the total length of the
Tunkua should be just a little bit longer than the elbow.
This weapon is the fourth
that practitioners of Matayoshi Kobudo Kodokan are introduced to. Officially the Kodokan curriculum includes the practice of kata and kata bunkai for this weapon. Originally this weapon was as the Tunkua, an ordinary household utensil. This utensil was used to smash grain and/or to peel off the bark of the Abaca or banana tree for weaving. This weapon, a difference from the Sai or Tunkua where the length of the forearm of the practitioner defines its size, does not have a specific way to measure it. The most common Nunchaku is formed by two lengths of 14" octagonal wood tied together by a rope.
