This video is a tutorial on how to do a bias-cut on a carrot. It is called the bias-cut because the cut keeps the same size on each piece of the carrot. A carrot is one of the most difficult foods to cut because it's shape is not uniform. You need to slice down at an angle for this reason. Your knife motion should not be choppy, but more wave-like. The bias-cut is important because it guarantees that the carrot slices will cook evenly.
