Cubikook CS-T01 3-Stage vs. Mueller 4-Stage Manual Sharpener Side-by-Side Comparison
The Cubikook CS-T01 and the Mueller 4-stage manual sharpeners are both decent sharpeners, but one is friendlier to the knife edge.
Specifications
Design
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.
The Cubikook is heavily function-oriented — it skips the bells and whistles and focuses on keeping the device sturdy, stable, and effective to use.
Usability
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 Cubikook has a straightforward design with a flat base, a sturdy working section, and an intuitive slot arrangement. Everything supports a safe and easy sharpening experience. It’s the best handheld sharpener for those with weak or shaky hands.
Performance
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.
The Cubikook performed consistently well in all four categories: speed, sharpness, material retention, and edge smoothness. As pull-through sharpeners go, this one is one of the most well-rounded options.

Conclusion
The Cubikook isn’t as fast as the Mueller; however, it’s the better choice if you’re about more than just speed.
We like the Mueller’s sizable and ergonomic grip and appreciate the handy scissor slot. The Cubikook sports a more pragmatic design, with a wide base and low center of gravity that ensure stability and safety.
The two sharpeners maxed at the same level of keenness—Level 8, which is the highest achieved by a pull-through sharpener to date. The Cubikook was outspeeded to the tune of 15 seconds by the Mueller in the lemon-cutting test. On the other hand, the former was friendlier to the knife, peeling off much less material and doing a better job of polishing the edge.
If you care about the longevity of your knives, the Cubikook’s gentle sharpening approach works much better.
