Sharp in 60 seconds

No skill needed. No guesswork. Just three simple steps.

01

Attach your knife

Place your knife on the magnetic guide. It locks in at the perfect 15° or 20° angle automatically.

02

Roll to sharpen

Glide the sharpener back and forth a few times. The diamond disc restores a razor edge in seconds.

03

Slice with ease

That's it. Your knives cut clean and smooth again — like the day you bought them.

Which angle do I use?

20° Most home cooks

Everyday kitchen knives. A strong, durable edge.

15° Advanced

Japanese-style knives. A finer, razor-sharp edge.

Not sure? Start with 20° — it's the right choice for most kitchens.
