The KitchenIQ 50009 and the Chef'sChoice 4643 Manual Sharpener may look completely different, but they achieved very similar ratings across the different tests we put them through.
Both devices have a strong and robust build. The KitchenIQ is a very compact sharpener that’s designed to stay securely on the edge of the countertop, while the Chef’sChoice has a more substantial size and works well on flat surfaces.
The former sharpens with tungsten carbide and ceramic blades, while the latter depends on diamond sharpening wheels.
And yet they garnered similar performance ratings, as neither went beyond average in our tests. Each took more than 3 minutes in the speed test whereas most others took less than 2 minutes and both are one notch below average in the level of sharpness achieved. Nor did they excel in edge preservation or polishing.
The choice between these two comes down to your personal preference. However, be advised there are better manual sharpeners out there, such as the Cubikook CS-T01 or the PriorityChef 2-stage sharpener.
