The Work Sharp Precision Adjust is the system we would buy first, because it solves the one problem that keeps kitchen knives dull: holding a consistent angle. A clamp holds the blade, an angle dial sets anything from 15 to 30 degrees in 1-degree increments, and a single Tri-Brasive rod carries three faces, 320-grit and 600-grit diamond plus a fine ceramic hone, so one tool handles repair, sharpening, and finishing. We took a chef's knife that had gone dull over a season of use, dialed 20 degrees, and about 30 minutes later it was shaving sharp. Check the current street price on Amazon for the Work Sharp Precision Adjust, though pricing moves week to week and typically runs about ten dollars below the $79.95 list price, so plan on about $70.

The system rewards a light touch, and that took us a session to learn, because the magnets holding the clamp and the sharpening arm are not the strongest we have used, and pressing down makes the angle wobble. Let the stone's own weight do the work, and the flex stops mattering. Photograph the clamp position against the angle scale on your first session, and you can replicate the exact angle next time, which is how beginners get repeatable results. Two limits showed up in testing: the 320-grit face is slow for reprofiling a chipped or badly neglected edge, and small low-profile knives like paring and fillet blades are nearly impossible to sharpen at or below 20 degrees without grinding into the clamp. Medium chef's knives, in other words, are its happy place.
With a 3-year warranty and abrasives rated for roughly 200-300 sharpenings, the base model is the easiest recommendation we make, and the ceramic face finishes well enough for most kitchens, though we add a 2500-grit lapping film on top when we want a true mirror finish. The upgrade kit and the Elite below cover the coarser-grit path without buying a new system.
