If the contestants could choose their weapons, I'm pretty sure a knight could batter down a samurai using a bludgeoning weapon. Mace + shield would probably be devastating. Catch the elbow on their sword arm with your mace and you'd have the fight won, I think. The whole while having a shield to cover your side. Bonus points if it's pine and catches the samurai's blade more often than not.As far as bows go... I'm not entirely sure on this, but wouldn't an European bow outrange/outpower a Japanese bow? I thought the japs used primarily those little recurved horsebows, which have a much shorter range than longbows. Crossbows beat both hands down in range, power and accuracy, but they take a lot longer to reload.
