KitchenIQ 50009 Manual vs SunrisePro Supreme Manual Side-by-Side Comparison

The KitchenIQ 50009 has more sharpening stages than the SunrisePro but that doesn’t give it any advantage in sharpness and speed. Check out our comparison.

Overall Design Scoring

Other than the inadequate size, there’s nothing to complain about in the design of the KitchenIQ. The device is symmetrical, sturdy, and has a decent fit and finish. It’s smart, simple, versatile, and highly function-oriented.

As small as it is, the SunrisePro is strong, solid, and sturdy. We could tell it’s made with attention to detail and quality.

Overall Usability Scoring

With only two sharpening slots and a basic design, it doesn’t require a high IQ to understand how the KitchenIQ works. The device’s small size may, however, mean you have to pay extra attention every time you use it or risk hurting yourself by misplacing the knife.

The SunrisePro’s suction mechanism may take some time to get used to, and even then, it can from time to time be challenging to get it to work properly. You may also want to be mindful of the sharpening pressure or risk having your blade eaten away by the device.

Overall Performance Scoring

The KitchenIQ failed the speed test and offered mediocre results in all other performance tests. Its rather small sharpening elements will sharpen your knives enough that you’ll be able to feel the difference, but not significantly. It will shave a lot of metal off your knives and leave a barely passable edge.

The SunrisePro offers faster sharpening than most multi-stage devices. Unfortunately, it does so at the expense of the knife edge.

Pros & Cons

  • Easy storage
  • Affordable price 
  • Base works on both counter edge and flat surfaces 
  • Simple, sturdy design
  • Strong, sturdy build
  • Extremely quick sharpening
  • Great sharpness 
  • Affordable price
  • Strong suction base (while it works)
  • Awkward small size
  • Long sharpening time
  • Suction base is surface-discriminatory
  • It can peel off a lot of metal


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.
