SunrisePro Supreme Manual vs Kitchellence 3-Stage Manual Side-by-Side Comparison

The SunrisePro admittedly delivers a sharper edge, but our pick is the Kitchellence where more than sharpness is concerned.

Build Quality
Overall Design Scoring

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

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

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.

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

  • Strong, sturdy build
  • Extremely quick sharpening
  • Great sharpness 
  • Affordable price
  • Strong suction base (while it works)
  • Easy to use, intuitive design
  • Soft, comfortable finish
  • Extra weight near the base for stability
  • Affordable price
  • Included glove for added safety
  • Suction base is surface-discriminatory
  • It can peel off a lot of metal
  • Tapered base 
  • Awkward base pad


The SunrisePro Supreme sharpener certainly gets the primary job done, but if you want sharpness with a smooth edge and consistent performance too, go with the Kitchellence.

The SunrisePro, despite having only one sharpening slot, does the job faster and more effectively than most devices we’ve tested. It also features a strong, sturdy build, and while we find the small size awkward, some may appreciate its compactness. Its problem is with the small edge it creates, which is sharp but blunts quickly. Also, its suction base, while strong on some surfaces, is useless on others.

The Kitchellence takes longer to sharpen your knives, and the sharpness level is also lower than what the SunrisePro can offer. But it’s still among the better performers in that respect. It’s also much more gentle to the edge than the SunrisePro. As a plus, it’s stable, natural to use, and comes in a size that we find more appropriate for kitchen knives.
