The Chef's Choice 4643 and the Zwilling are multi-angle sharpeners and both belong to the more expensive side of the price spectrum. Unfortunately, neither offered a performance to match its price.
Each took 4 and 3 minutes respectively to complete our speed test, against an average of a few seconds over 2 minutes. They both produced a sharper edge but not to any significant degree. The former fared better in terms of material retention while the latter produced a smoother and straighter edge.
The Chef's Choice 4643 enjoys better stability thanks to its wide base and low center of gravity. The Zwilling sharpener, while seemingly made of premium materials, features a narrow body that kept threatening to tip over during sharpening.
