So basically samurais weren't trained how to hold a sword ;\ And the samurai technique is non-existent.
Just like most soldiers don't really know how to hold or use their weapons and they are never trained
I'm pretty sure FUEDAL JAPAN is really the ONLY time-period in which samurai's were bad asses, since after feudal japan was obliterated and absolutism rose during the meiji restoration the samurai class was essentially abolished, and all swords were taken away during the great sword hunt.
