Build Quality
Overall Design Scoring

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.

The Longzon looks identical to the Mueller handheld sharpener and has a much better build and design than its affordable price suggests. There’s no shoddy parts or gimmicky details — everything fits together securely and seamlessly to serve its purpose.

We also like the device’s substantial size which allows for easy sharpening of larger kitchen knives. The inclusion of the gloves is nice, though we didn’t feel the need to use them.

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.

The Longzon is straightforward, and there are visual cues on the device if you’re not sure how to use it at first glance. Its large grip and wide working section make sharpening natural and effortless. Though we think a more modest height would make it safer to use, its stability is well above average.

Overall Performance Scoring

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.

The Longzon 4-stage knife sharpener creates one of the finest edges we’ve seen with a device of this type. Unfortunately, the edge’s functionality doesn’t match up with its aesthetics. It only became keen after more than 3 minutes of sharpening, and a prolonged sharpening time didn’t get it much further on the sharpness scale either.

  • Substantial, accommodative size
  • Fine, smooth knife edge
  • Inclusion of protective gloves
  • Slot for scissors
  • Tapered and bumpy base
  • Poorly fitted rubber feet
  • Tall base
  • Slow sharpening
  • Ineffective slot layout


The Gorilla Grip and the Longzon 4-stage sharpeners both enjoy a decent build, with the latter having a better fit and finish. However, their actual performances couldn’t have been more different.

The Gorilla Grip excelled in speed and sharpness but forwent the actual quality of the knife’s edge. It shaved off the steel like no other, leaving the edge jagged and wavy. The Longzon was the opposite: It took more than double the time to sharpen to the designated keenness level and could only reach a sharpness level one below its competitor's best but material retention and edge aesthetics proved to be top-notch.

In the end, because keenness and speed are more important factors than edge integrity in a handheld sharpener, the Gorilla Grip ended up with a higher overall score.
