P.S. Saito's kumitachi end with the attacker being killed (although a step back rather than step forwards is sometimes used for safety). An exception to this is the 5th kumitachi where the roles of attacker and defender type of 'swap over' midway. With the kumijo this is also the case for the first few, although the last ones do involve 'opportunities to strike the attacker which aren't used'. Don't forget also there are 2 sword variations (and 2 taijutsu variations) for each kumitachi form under saito.
