You did what with that Lada?

[Timbuktu]

No one needs to hit a bland band of metal with a katana if you know how to wield it.
You just need to guide and defend.

Actually, real sword fights, especially katana fights, aren't like you see them in movies. They rarely last longer than 5 seconds.
In a real katana fight, if you tried to defend and havent managed to chop something out of your oponent within the first 2 seconds, you'll certainly not be in one piece at the end of the fight.
