I was wondering if using three swords with the third in your mouth would be effective against anyone else with a sword. I'd think so, because you could parry their attacks, and then slice them with the third blade by moving your neck.
Here's an example of triple sword wielding.
First of all, please no. Just don't.
And no, it will not be effective. Even given that there are some people that can tow trains by ropes in their teeth, you cannot clench your jaw enough to be able to hold on to it if someone hits the blade. It will spin out, and if you are lucky, leave your teeth behind.
Second, despite what they show in cartoons, you are much more likely to hit the sword yourself, either on the way through for a strike or when drawing back. Add to that, you can't really generate enough force to cut deep enough to do the damage you want merely by twisting your neck around, unless you get lucky.
So in effect, you are risking a lot of damage and limiting your effective attack. Even your right hand sword (as shown in the picture) will be of limited effectiveness since you are only using one hand and missing the "push pull" action that gives your strikes the most force.
I have at least three things to say.
I HIGHLY doubt the triple sword style would be effective in real life. And even if that wasn't the case, Zoro is darn near superhuman, which is probably why he is the ONLY one who mastered this style.
Is that YOU in the picture?
If this is you in the picture, I have to say you are both bold AND reckless. If this is what it looks like, you are not only risking your modesty by posting yourself butt naked, you are also risking your the health of your teeth and "other parts" by carrying THREE sharp, presumably heavy swords, knowing one wrong move could do a LOT of damage. The three sword style is impossible, but for this bravery, I commend you dude.
