The PriorityChef is the obvious choice over the KitchenIQ.

Both sharpeners are well constructed. The former comes in an awkwardly small size but its selling point is its special EdgeGrip base. The latter sports a sizable body that feels more natural in an adult’s hand, but would benefit from a stronger base.

Both come with two sharpening slots, though they have different abrasives: the KitchenIQ features carbide and ceramic blades, while the PriorityChef sports diamond discs. 

When we put them to the sharpening tests, the PriorityChef proved to be far superior in all parameters: speed, sharpness, material retention, and edge smoothness. The KitchenIQ displayed a mediocre performance at best and is simply not a match.
