Moonduck:
I find the assumption that a "...Samurai would own a knight easily." to be a bit brash; and I think that Japanese Sword Techniques (Ken-Jitsu/Kendo) are over rated. I've spent quite a while training in both and I've found that there is a wealth of both Sword and Unarmed Combat Arts from Europe that (IMHO) are just as effective as anything from Japan.
No offense NeverBorn, but as was mentioned by other people in this thread the simplistic comparison of a "Knight" VS a "Samurai" is not really specific enough (time period, Nationalities, Equipment... etc) to assume anything.

the Society for Creative Anachronism is a Medival Recreationist group the seeks to relive the middle ages the way it ought to have been. Including full contact "Sword" Combat.
