> If you're the type of person that would only sharpen knives once a year because it takes half hour to set up your sharpening rig and sharpen your knife, get an electric sharpener instead
This is an obsolete dichotomy. There are excellent modern low-porosity stones that you can get wet and use immediately. For example, resin bonded diamond (e.g. CGS, Venev, Naniwa Diamond), Shapton Glass (unspecified “ceramic”), or diamond-in-nickel (DMT).
The idea of a long progression of expensive stones seems to be almost entirely a myth — there seems to be no actual benefit, and possibly quite a bit of wasted time and increased chance of entirely failing to get a good edge, if you use a zillion different grits. A cheap coarse stone or two and one (expensive) medium-fine stone is plenty, and you won’t touch that coarse stone if your knife is already in decent shape. Throw in a strop loaded with a decent abrasive and you can maintain your knife in a minute or two.
(I use a cheap balsa wood strop loaded with 1 micron CBN suspended in water. Total setup time to strop a knife is however long it takes to get it out of a drawer. WEAR A REAL MASK and work outside while applying the CBN — I seriously doubt that inhaling a fine mist of tiny minerals is a good idea.)
