The key to great knife skills is having a sharp knife. More accidents in the kitchen come from having a dull knife as opposed to a sharp knife. You can sharpen your knife on a honing steel (as shown in the video) or with a stone. I am not a fan of electric sharpener's because they shave off to much metal but those are also available. You want to sharpen your knife each time you use it. That will keep an edge on your blade. This video shows proper technique for sharpening your knife with a honing steel.
