Gorilla Grip 3-Stage vs Mueller 4-Stage Sharpener Side-by-Side Comparison
Gorilla Grip 3-stage vs. Mueller 4-stage sharpener: Check out how they compare when faced with the same sharpening tasks.

Specifications
Design
The Gorilla Grip looks almost identical to the Amesser and the Kitchellence: It has a tall but weighted body, a tapered base, an ergonomic grip, and a soft cover. Unfortunately, the shaky base and the poorly fitted rubber pad set it back by a few points.
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.
Usability
With a straightforward design, the Gorilla Grip is easy to use. We didn’t record any difficulty while inserting the knife or pulling it through the device’s sharpening slots. Stability could be improved, but we didn’t have to tire our wrists to keep it in place during sharpening.
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.
Performance
The Gorilla Grip seems to be the opposite of the Kitchellence in this regard. It sharpens quickly and effectively but can peel off a lot of material from your blade. Despite the ‘Polish’ slot, our test knife ended up with a rough, uneven edge.
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.

Conclusion
The Gorilla Grip 3-stage and the Mueller 4-stage sharpeners have more similarities than differences.
Both devices feature three sharpening slots for kitchen knives—the Mueller having an extra one for scissors. Despite the difference in slot order, they are among the top performers in terms of speed—the Mueller being slightly faster—and sharpness. The two are also among the least forgiving when it comes to preserving edge smoothness and saving knife material.
Both sharpeners sport a substantial body with an ergonomic handle. The Gorilla Grip is a few points behind due to its bumpy base and subpar finish. The Mueller has a high center of gravity, which isn’t good for balance and stability, but some users may find its scissors slot a handy plus.
