Mueller 4-Stage vs Longzon 4-Stage Sharpener Side-by-Side Comparison

Overall Verdict
Apart from their logos, the Mueller 4-stage and the Longzon 4-stage sharpeners look identical. They have a robust build and sturdy construction. Both feature three sharpening slots for kitchen knives and one for scissors. Both sharpeners suffer slightly from a high center of gravity.
When put through the test of sharpening, interestingly, the sharpeners garnered very different results. The Mueller compromised the knife’s edge for quick sharpness, while the Longzon prioritized a smooth, shiny edge over sharpening time and serviceability.
In the world of ‘convenience’ manual sharpeners, the one that makes the knife cut first has an edge, so the Mueller seems to be the more practical choice.
