There's a bunch of things wrong here...

1. knights wear heavy armour making them slow in running but protects them against many attacks.
Alright, this one may pass [img]tongue.gif[/img]
2. a ninja wears very light armour and can be cut easly but the lack of armour makes them very agile.
You need to decide wether he is fighting a samurai or a ninja.
3.knights are allowed to parry and dodge but ninja's are not allowed to.
Why are ninja's not allowed to dodge? Ninja's life depends solly on dodging blows, and evading attacks.
4.lonswords make it harder to swing when a katana is light and quick.
Their weights are the same, it's just that the katana has the center of mass closer to the hilt, makin it slightly quicker but less powerfull. Not to mention that ninjas don't use katanas.

Samurai katanas are designed to cut through wooden armor, the type the samurai and the other troops normally had, whereas the longsword is for bashing at chainmail, plate and the like. The two are incomparable, unless the one wielding the longsword were to have the wood and reed armor, and the samurai would be clad in plate mail. And then the whole thing drops as the weapons are not used with the equipment they were meant to be used with. This topic has been done to death, resurrection and then death again, and the conclusion is that the two would NEVER FIGHT AN EVEN FIGHT.
