This is the knife fighting part of our training.
It is usually taught after the student fully understands all the aspects of alimentation and body movement.

Traditionally the Tanto was used as a suicide weapon.
It was generally understood that if you could not complete your mission you would disgrace yourself and your school or clan, and the only way to keep from dishonoring your clan would be to commit ritual suicide using your own blade (usually this was done with the Tanto).
