Spyderco make a very good easy to use sharpener that will give you a razor sharp edge at either a utilility angle of 22.5deg each side or fine cutting angle of 15deg each side of the blade. They are called the Spyderco triangle sharpener and will sharpened everything from serrated edges to fish hooks. I have one and can vouch it works. They are not a mechanised sharpening device and all sharpening is done by hand on ceramic stone. Before you buy anything these are worth a look.
