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.

We fell in love with the Kitchellence the moment we had it in our hands: It’s neat, simple, and strikes an excellent balance between aesthetics and functionality. We could tell the maker of it paid attention to every detail.

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.

Its weight and design makes the Kitchellence a breeze to use: if you know how to use a knife, you will have no problem working with this device. The only mild problem is when you try to sharpen on a wet surface — but hey, it’s not hard to give your countertop a quick wipe, right?

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 Kitchellence could bring the knife to a serviceable keenness level without peeling a bunch of swarfs off the blade. However, it was slow to sharpen, which defeats the purpose of a ‘convenient sharpener’.

Pros & Cons

  • Easy storage
  • Affordable price 
  • Base works on both counter edge and flat surfaces 
  • Simple, sturdy design
  • Easy to use, intuitive design
  • Soft, comfortable finish
  • Extra weight near the base for stability
  • Affordable price
  • Included glove for added safety
  • Awkward small size
  • Long sharpening time
  • Tapered base 
  • Awkward base pad


It may cost a few dollars more, but we’d pick the Kitchellence over the KitchenIQ every time.

The KitchenIQ is made with durable materials giving it a strong build. Its ability to stay on an edge also garners extra points. However, its performance was far behind the Kitchellence’s and below average in all aspects. Its small size, while appealing as an on-the-go sharpener, also makes it a little awkward and potentially dangerous to use.

The Kitchellence, on the other hand, scores well on size, design, and build quality. It takes its time to do the business, but in the end, offers decent sharpness and a smooth edge. The device also removes much less material from the knife edge compared to the KitchenIQ.
