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.
