Sharpening a knife can bring a dull edge back to life. This video tutorial shows how to sharpen a knife using a whetstone. Soak the whetstone in cold water for about 5-10 minutes and set it on a clean towel. Starting with the coarser side, push the knife against the stone while applying downward pressure. Apply more pressure on the forward stroke than on the back. Wipe down the knife and flip the stone over to the fine side. This will smooth out the knife and make a sharper, finer edge.
