I was looking for a good sharpener system a while back and wound up buying the WorkSharp Ken Onion Edition. Been working with it on a few knives and it's just not doing it for me. Just cannot get a good edge. In fact I'm dulling knives, not sharpening them. Been following the manual but I remember that couple guys here use them and was wondering if there are some tips or techniques I'm missing? Maybe it is just me.
