There are several different methods of knife sharpening and the way in which you would sharpen a knife depends on the type of sharpener that you choose to use. Some people like to use an electric sharpener which makes the job easy for you as you just allow the machine to do its job. A sharpening stone can also be used; this is a type of stone that is used with oil or water. If you have a water stone then you will need to soak it under water first for around 5 minutes and then slowly move the blade from side to side across the stone on both sides with your hands flat against the "safe" part of the blade. There are lots of YouTube videos that demonstrate this beautifully. You can also use a sharpening rod which is used slightly differently. Again, YouTube is a useful source for these videos.\r
