Ceramic sharpeners definitely have their place. The truly exceptional one is the Spyderco Sharpmaker 204. Takes the crock stick idea up a couple of levels. It even does a good job on serrations. Right now I'm currently in love with my Spyderco bench "stones". I like freehand sharpening on a lot of different edges, but had gotten lazy about the oil, and such. Therefore I wasn't sharpening some of my knives as much. With the ceramic I just scrub it down with an abrasive cleaner (like Comet, Soft Scrub, Bon Ami, etc.) and a green scotch brite pad.
