<human>: How do you do this: To chop onions

OPTIONS:
- Place your onion on a chopping board, remove the top of the onion with a knife, then cut from the top down to the root to cut the onion in half. Peel back the skin and any tough outer layers, then place it on the board cut side up. Use the knife to cut parallel to the chopping board from the top down to the root, from the side furthest from the board to just above it. Do this many times for a fine dice, or just a couple for large sections. Turn the knife around so the sharp blade points down at the board and the point points toward the root, and do the same thing again from left to right. Finally, turn the knife so the blade points down at the board and the point points parallel to the root, and cut slices from the farthest part of the onion away from the root, to close up to the root. Remove the root, and chop the onions with the knife in a rocking motion if need be, holding the blade rightly just above the handle between thumb and forefinger.
