I am a profoundly mediocre sharpener. I can, however, keep them in fighting trim if I have a good edge put on them by a professional first. This goes for my kitchen Wusthofs, my Bucks, and my SAKs. I don't have any special kits or sharpening "systems" (why is everything a "system" now, anyway?) just a couple of ceramic sticks, an Arkansas stone, and a massive medium-grit DMT block I inherited with most of my knives. They do the job when the main bevel has been set. If I need more than these can provide, I'm off the Parker Farmer's Market on Sunday to visit the knife man. My Dawson Sheffield Bowie was IMPOSSIBLE for me to put an edge on and two knife pros told me the hardness of the steel was more than they had encountered in some time (it's shaving sharp now, thanks to one of them). I think you want to decide how good you need to be and then work from there. Buy the knife you need/want/can use and then learn to do what you need to do to keep it in shape. If you want to be an auto mechanic, learn to be a mechanic. If you only want to change your oil and air filter, then just learn that. But you'll still get the vehicle you need/want/can use, right?
