I'm a bit of a lousy cook and looking on amzon.com the other day I discovered this- a bargain knife sharpener. If your not someone who wants to spend hundreds of dollars on kitchen supplies this is most certainly for you. It's not exactly amazing, but it does a pretty good job. As good as some of the models for twice its price. It will almost make them as good as new.
It's also very easy to use, just run your blade firmly down the ceramic wheel a couple of time, and voila! I've managed to sharpen every knife in my drawer in about 5 minutes. It is also quite small so it doesn't take up a lot of counter space its also means it's ideal to take on camping or hunting trips.
So far I haven't encountered any problems with this! overall it's a pretty flawless product that I would highly advise any chef to use.
