# 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.

## At a glance

- The listing describes the diamond disc as suited to reshaping and the finer ceramic disc as suited to honing and polishing.
- The 15° and 20° magnetic guides provide preset angle options rather than an adjustable angle range.
- Replaceable discs are claimed, though replacement availability is not specified.

## 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.

## A good fit for

- Home cooks wanting a manual sharpener with preset 15° and 20° options.
- Knife owners seeking both a coarse diamond disc and a finer ceramic disc in one kit.
- Buyers who want a stated leather strop and magnetic knife holder in the package.

## Less suited to

- Buyers needing a powered sharpener or a freely adjustable angle.
- Anyone who requires confirmed compatibility with a particular blade type before purchase.

## Customer feedback

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.
- Positive themes: Customers report that the sharpener is easy to use and can produce sharp edges.
- Positive themes: Feedback also describes the product as well made and favorably priced.
- Mixed feedback: Reports about the magnetic attachment conflict: some customers say it does not slip, while others consider the magnet weak.
