Okay, so pony wanted me to teach her how to sword, and I was like I'll just post it.
HOW TO FUCKING SWORD YO
First off, people like to let their wrist go loose when they swing. Don't do that, it softens the blow.
Second, choking up on it is a valid option. If you're swinging, it speeds up the tip of the blade and gives you a little more control. I only recommend this if your sword has a non-sharpened part by the handle, if it is sharp down to the handle, don't do it. You'll cut the shit out of yourself. It's also very effective in CQB
