I also am 6'1" and I fight in the SCA, so believe me when I tell you I know how to use a sword. Anyway, me and a bunch of my SCA fighter buddies have dueled full force, full contact, with the intent to injure eac hother or break them. The best we could to is shatter one of the acrylic tips and put a crease in the middle of the blade. But mind you, that crease was only put there after beating the thing full force on everything we could find and about 10 people bending the thing over there knee giving it everything they had.

***It is now that we battle.When you die, await my arrival in the afterlife where we will battle again.Perhaps there you may have the ability to defeat me,but not here,not now,not this day.So let us part with words and embrace the blade.***
