I love this little video because he tells you EXACTLY how to position your hands and your knife to cut properly and safely. Well, with one little exception and that is that the knife top should always have contact with the cutting board. He does it, he just doesn't say it. Watch carefully.
And by the way, the name of both videos is "5 min" but the first is a minute and a half and the second is two and a half minutes, not five.
This is my snobbery at work. It makes me crazy to watch the non-chefs on Food Network chop stuff. I thought Robin Miller was going to cut her fingers off the other day. She was sort of chopping with the knife completely lifted four inches off the board, plus it took her forever. I know that Giada has been to culinary school but it sort of makes me crazy to watch her chop too. But watching Emeril, Bobby, or Alton chop is like watching dance, it's a thing of beauty and goes by in a blur.
Here's another video that shows an actual dice and chop of several vegetables. It's not quite as smoothly done but a good primer. Notice how, again, once the dicing begins the knife keeps contact with the chopping board and the cutting goes in a rocking motion.
I do have a bone to pick with them when they show mincing a garlic clove the same as chopping an onion. My personal opinion is that that's a good way to cut your fingers. It's just to small. I make all the cuts all the way through to keep my fingers out of the way. Those horizontal cuts they made were scary, I thought!
But the video is very informative in general:
