Muso Shinden Ryu
Iaido (居合道 Iaidō or Iai 居合) is a modern Japanese martial art/sport, where the term 'iaido' appeared in 1932. Iaido is associated with the smooth, controlled movements of drawing the sword from its scabbard or saya, striking or cutting an opponent, removing blood from the blade, and then replacing the sword in the scabbard.
While new students of iaido may start learning with a wooden sword (bokken) depending on the teaching style of a particular instructor, most of the practitioners use the blunt edged sword, called iaitō. Few, more experienced, iaido practitioners use a sharp edged sword (shinken).
The Iaidoka (a practitioner of iaido) wields a sword: not to control the opponent, but to control himself. Iaido is mostly performed solo as a series of Waza. The Iaidoka executes various techniques against single or multiple imaginary opponents. Each Waza begins and ends with the sword sheathed.
In addition to sword technique, practitioners require imagination and concentration in order to maintain the feeling of a real fight and to keep the Kata fresh. In order to properly perform the waza, Iaidoka also learn posture and movement, grip, and swing. Iaido is never practised in a free-sparring manner.
