Sage-0 no Kata (Sword String Form)

The Togakure Ryu Ninjutsu uses a small iron weight (fimdo) attached to the end of the Sageo. This was used as a form of Metsubushi when it was used for fighting. There were countless other applications for this as I am sure you realise (for when the Sageo is used as a rope). It was also common for the Sageo to have an egg filled with Metsubushi attached to the end of it. For these reasons, the Sageo was usually concealed inside the jacket. The Saya was also used as a form of Metubushi.

Sono Ichi (Number 1)

You begin in Shizen Tai. The Uke begins in any Kamae. Place the Sageo in your right hand The Uke begins to attack. At the point of attack (same principal as in the technique "Metsubushi") you throw the Metsubushi that is attached to the Sageo at the Ukes eyes. At the instant the Uke flinches, you draw your sword and cut.

Success without honor is an unseasoned dish; it will satisfy your hunger, but it won't taste good.
