Our take on the Knivratix

The Knivratix is a rolling knife sharpener: a magnetic base holds the blade at a fixed angle while a diamond-coated disc rolls along the edge. The base offers five angle settings (12°, 15°, 17°, 19°, 22°), and two discs, 400# for grinding and 1000# for polishing, cover dull edges through light honing. It needs no water or power, which makes it simpler to set up than electric sharpeners and easier to control than a freehand whetstone. It suits home cooks who want repeatable angles without learning freehand technique; buyers wanting a mirror polish or heavy repair of chipped blades will find the two-grit setup limited.

Best forHome cooks who want consistent edge angles without freehand skillKitchen owners who prefer a no-water, no-power sharpenerPeople sharpening a mix of Western and Asian knives at different anglesSmall kitchens with little counter or storage space
Pros
  • Magnetic base holds five fixed angles from 12° to 22°
  • Rolling motion keeps the disc square to the edge along the whole blade
  • Two diamond discs: 400# to grind, 1000# to polish
  • No water, oil or electricity needed
  • Natural wood body is compact and easy to store
Cons
  • Two grits only; no coarse option for chips or reprofiling
  • Diamond discs wear and are the part that needs replacing
  • Rolling technique still takes practice to keep pressure even
  • Not a substitute for a honing rod between sharpenings

About the Knivratix

Knivratix is a rolling knife sharpener with a natural wood body and two diamond discs. You push the roller across the blade to sharpen it. It needs no water, oil or electricity.

A magnetic base holds the knife at one of five set angles: 12°, 15°, 17°, 19° or 22°. The 400# diamond disc removes nicks and reshapes the edge. The 1000# disc then polishes it.

It is made for straight-edge knives, including Damascus steel knives. It does not work on serrated knives.

Questions and answers

How does a rolling sharpener differ from a whetstone?
The magnetic base fixes the blade at a set angle and the disc rolls along the edge, so you don't hold an angle by hand. It is faster to learn than freehand stone sharpening, but a stone offers more grit choices.
Which angle should I use?
Match the angle your knife was made with: Asian-style blades usually take 12° to 15°, most Western kitchen knives 17° to 20°, and heavy outdoor or cleaver edges 22°. Keeping one angle per knife gives the most even result.
Can it repair a chipped or very dull blade?
The 400# disc can reset a dull edge, but it is not a coarse grinding wheel. Deep chips and reprofiling are better handled by a coarser stone or a professional sharpening service.
Do I need water or oil?
No. The diamond discs are used dry, which keeps the process clean and means no soaking or mess on the counter.
How long do the diamond discs last?
Diamond abrasive slowly wears with use, and the discs are the consumable part. Light, regular passes extend their life more than heavy pressure.
What is in the box?
The sharpener comes with the wood rolling body, the magnetic angle base and the 400# and 1000# diamond discs.
