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.

Despite its affordable price, the Muller 4-stage sharpener has a strong, solid build, substantial abrasives, and tightly-fitting parts. It has a nice fit and finish and a spacious grip that’s comfortable to the touch. However, a lower working section would offer better control and stability.

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?

Though the Mueller is a bit tall, it offers decent balance and stability. Its large size and substantial abrasives give you a lot of confidence when sharpening. The slot layout could be improved, in our opinion, but it doesn’t pose much of a problem in terms of usability.

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’.

It won’t make your knife razor-sharp, but the Mueller takes little time getting a dull edge ready for common cutting tasks in the kitchen. Contrary to its twin, the Longzon, however, it eats away the blade and leaves a rough, uneven edge.

Pros & Cons

  • Easy to use, intuitive design
  • Soft, comfortable finish
  • Extra weight near the base for stability
  • Affordable price
  • Included glove for added safety
  • Strong construction, pretty coloring
  • Quick sharpening
  • Scissor slot
  • Ease of use
  • Tapered base 
  • Awkward base pad
  • High center of gravity
  • Harsh on the knife edge

Conclusion

The Kitchellence 3-stage and the Mueller 4-stage sharpeners are well-built devices. The former has a solid construction with a nice finish while the latter has a sizable body with an extra slot for shears and scissors.

Both would benefit from a lower working section, though the Kitchellence does better in terms of balance, thanks to a metal plate near the base that adds weight and stabilizes it.

The Mueller can sharpen faster and to a higher level of sharpness. The Kitchellence, on the other hand, is much gentler to the edge. 

Your choice between the two thus comes down to what your priority is: If you don't mind spending more time to get a smoother edge, get the Kitchellence. If speed is important, go with the Mueller.
