The KitchenIQ and the SunrisePro manual sharpeners are both small devices but both are also well built with a sturdy construction. 

The KitchenIQ has a more straightforward design. Its base works both on a flat surface and the edge of a table or countertop, giving it a level of versatility few others enjoy. The SunrisePro, meanwhile, requires a clean and flat countertop that its suction cup can stick to, otherwise its tiny body makes it tricky to sharpen with.

When it comes to speed and sharpness level, however, the SunrisePro really stands out. It took one third the time the KitchenIQ did to transform a dull knife to a highly serviceable level. It brought the knife one level higher on the sharpness scale too in our maximum sharpness test. It did produce a slightly rougher edge but we’d take that over spending more time for a less-keen edge.
