Overview
A rolling knife sharpener with a diamond disc, a ceramic disc, and a leather strop built into one wood based unit, designed for straight edge kitchen knives.
The two angle guides, 15 and 20 degrees, are magnetic rather than adjustable dials, which locks the blade to a fixed angle instead of relying on freehand consistency. It is built for straight edges; the listing itself excludes serrated blades and scissors from what it can sharpen.
- #400 diamond and #3000 ceramic discs
- 15 and 20 degree magnetic angle guides
- 4 N42 magnets hold the blade in place
- Leather strop included for finishing
Who it's for
Suits home cooks maintaining kitchen knives who want a repeatable angle without freehand sharpening skill. Not a fit for serrated bread knives or scissors, which the sharpener is not designed to handle.
Pros and cons
- Fixed magnetic angle removes freehand guesswork
- Diamond plus ceramic discs cover both stages of sharpening
- Leather strop included for a finished edge
- Not designed for serrated blades or scissors
- Only two angle options, 15 and 20 degrees
Performance notes
Sharpening happens in stages: the #400 diamond disc removes the worn edge first, the #3000 ceramic disc polishes it, and the leather strop clears any remaining burr afterward. Four N42 magnets hold the blade against the chosen angle guide, either 15 degrees for a finer edge or 20 for a more durable general use edge, so the angle stays constant across the length of the blade.
