I use a Gatco kit at home when I need to reestablish an edge on hunting and pocket knives. I mostly use either a steel rod or the Rapala unit Stealhead posted on kitchen and fillet knives, but occasionally use a large stone. I don't carry sharpening gear in the field anymore, but always have a main knife and a smaller back-up (which I very seldom need).
I used to have a steady enough hand I could get a shaving sharp edge on most any knife, but I seem to have lost the touch. The above works well enough for me to keep them plenty sharp...
