Like Mack said, if you have never sharpened them the ceramic stones work pretty good. There are a couple of videos on YouTube on how to do it. Never used the work sharp but have been told it will work to some degree. Like he said you wil eventually wear them down. I thought about trying a Dremel tool and chain saw sharpening stone to work on the groves. But that seems like a lot of work for the result that you might get.
