     It is 
    claimed that Kamiizumi created the practice sword called the shinai 
    (bamboo sword), which is made of strips of bamboo inside a leather pouch. 
    The shinai allowed striking with quickness, fluidity and potency without 
    causing serious or disabling wounds as one would with the wooden sword, and 
    without having to stop the attacks.He began to advocate the utilization of 
    light armour during training.He also changed basic postures by raising them 
    slightly. He also changed the manner of holding the sword. 
    The form 
    was codified by Yagyu Toshikane the fifth heir to the system and it includes 
    aspect of Bojutsu, Kenjutsu and Shurikenjutsu..  |
