Cubikook CS-T01 3-Stage vs. Longzon 4-Stage Manual Sharpener: Side-by-Side Comparison

Overall Verdict

The Longzon 4-stage sharpener gave a decent performance in most of our tests, especially when it came to edge material retention and edge sharpness. However, it  was mediocre in the deciding ones, such as sharpness and sharpening time. Other than that, it’s a well-made, sturdy, straightforward piece of equipment.

The Cubikook CS-T01 3-stage sharpener comes with its own flaws, namely a poorly attached brand label and a shoddily-fitted ceramic rods; yet, it found itself among the top in all parameters. With a practical design and strong construction, it offered great stability and was among the safest and easiest to sharpen with.
