The worksharp is mainly for sharpening dinged chisels, plane blades, etc. final honing is done on stone, though I use diamond plates (lazy). I would not use the worksharp on a good knife as it will take it down really fast. It is designed to reform bevels on wood working tools, lathe and caarving tools, etc.
As far a skill in sharpening, it is nothing but time spent to build that skill. I have a bunch of chisels, plane irons, and gouges that I can let you practice on.
