Chef's Choice 4643 EdgeSelect vs. Longzon 4-Stage Manual Sharpener Side-by-Side Comparison
A side-by-side comparison of the Chef's Choice 4643 EdgeSelect vs. Longzon 4-stage manual sharpener.
Chef's Choice 4643
Tested Using Methodology v1.1Longzon 4-stage
Tested Using Methodology v1.1Overall Verdict
The Longzon is not the best sharpener on the market, but it’s the better choice between the two.
The Chef’s Choice 4643 sports an ergonomic and well-balanced design. Unfortunately, its abrasives didn’t do a great job of sharpening: The device was slow to sharpen and didn’t create a smooth edge. It also didn’t bring the knife very far on the sharpness scale.
Whereas the Chef’s Choice designates a slot for a different grind angle, the Longzon has one for sharpening scissors. The Longzon could only sharpen to the same level of edge keenness; however, it took less time to do the job and did leave a much nicer knife edge, which contributes to its higher overall rating in the end.
