It's amazing what you can find on the Internet. It's been years since I practiced karate, and I never really memorized the names to begin with, but I recognize the
Heian Nidan as one of the katas I practiced. Hell, I think that may be the one that I did when I got fifth place in that karate tournament.
I'm not bragging or anything, mind you. That's one of the simplest katas there is.
