Bogoni BO Rolling Knife Sharpener, Diamond and Ceramic Discs

Discs: The Bogoni BO rolling knife sharpener pairs a 400-grit diamond disc for reshaping with a 3000-grit ceramic disc for honing and polishing. Preset 15° and 20° magnetic angle guides offer two edge-angle choices, while the manual rolling format requires moving the tool along the blade.

The listing describes the diamond disc as suited to reshaping and the finer ceramic disc as suited to honing and polishing.

Pros and cons

Pros

Two abrasive stages cover reshaping and finer honing or polishing in one listed tool.
Preset angle guides reduce the need to hold an angle freehand.
The listed kit includes a leather strop, magnetic knife holder, and gift box.

Cons

The two fixed angle choices offer less flexibility than a sharpener with a continuously adjustable angle.
Sharpening is manual, so the user must guide the roller along the blade.

Customer feedback highlights perceived sharpening effectiveness, ease of use, sharpness, and build quality. Some customers describe the magnetic attachment as holding without slipping, while others say the magnet feels weak. That concern matters because the listed sharpening method relies on a magnetic knife holder, so buyers who prioritize a particularly firm hold should consider the mixed reports. Customer feedback also describes sharpening as quick, but actual time can depend on the knife and its condition.
