Zwilling 4-Stage vs. Longzon 4-Stage Manual Sharpener Side-by-Side Comparison
We put the Zwilling 4-stage and Longzon 4-Stage sharpeners through a series of tests to see how they measure up. Here’s our detailed comparison.
Zwilling Henckels
Tested Using Methodology v1.1Longzon 4-stage
Tested Using Methodology v1.1Overall Verdict
The Zwilling 4-stage and the Longzon 4-stage sharpeners are well-built, robust sharpening devices, but that didn’t help them score well in our sharpening tests.
The Zwilling 4-stage has a solid body that is certainly made of high quality materials. Unfortunately, its fancy design features were not very useful in practice—its thin and narrow base did not help with balance, while the supposedly ergonomic handle proved awkward to grasp. The sharpener was also one of the slowest to show results.
The Longzon offered better balance and ease of use during sharpening. It was gentle to the knife and created an extremely fine edge. However, the improvement in sharpness was modest compared to other sharpeners. The device took longer to achieve sharpness than most sharpeners as well.
Between the two, the Longzon is the more acceptable choice. But there are better performers—take a look at our rating tables to find the right one for you.
