Although I use a crock stick type of sharpener in the kitchen I usually use bench stones on my other knives. When sharpening the clip blade on a pocket knife that I got for Christmas I noticed that the blade had been shaped so that a LOT of material had to be removed in order to get a consistent bevel on the entire edge, due what appeared to be a curve in the edge towards the handle that resulted in a low point. A crock stick type of sharpener probably would have followed the curve of the edge, and would allowed me to sharpen without removing so much material. But, once sharpened with the benchstone I can use either a benchstone for touch up later on or a crock stick if choose to.
