Simpler. Safer. Sharper. CATRA Technology for Your Kitchen

Sharp knives are essential for your kitchen; Reduce stress and strain on your hands, wrists and arms; Reduce food waste with more precise cuts; Reduce risk of injury, as blunt knives can easily slip. Designed to the same exacting standards as our larger commercial machines, the CATRAHONE Diamond Power sharpener provides your home with high quality sharpening to factory levels of sharpness.

Here are more reasons why the CATRAHONE is one of the best domestic knife sharpeners in the world:

  • Suitable for all sizes of plain-edge knives, including concaved edge knives such as pruning knives.
  • Capable of re-sharpening utility knife blades.
  • Achieves consistent sharpness between different knives.
  • No skill required, just plug in and sharpen – if you can use a knife you can use a CATRAHONE!
  • Creates a smooth honed cutting edge, not a torn jagged one.
  • Unlike many other domestic sharpeners, it does not scratch the blade sides.
  • Restores worn cutting edges in under 2 minutes.
  • Diamond honing wheels allow maintenance sharpening in less than 20 seconds per knife.
  • Easy to clean and maintain – dust magnet reduces contamination to work surfaces.
  • Lightweight and portable, strong plastic body, non-slip rubber feet on the base.
  • Safe to use with no open moving parts.
  • Designed and developed in Sheffield, the Steel City.
  • Left-handed version available, providing natural comfortable operation for left handers.

The CATRAHONE provides the user with three operating slots, each with its own purpose:

  • ONE: Restoration of very worn blades
  • TWO: Everyday sharpening of most blades
  • THREE: Final super smooth honing

The CATRAHONE does not need water cooling, yet does not over heat the cutting edge. This provides your blades with an edge that is twice as durable than other electric sharpeners can provide. Compared to a sharpening steel, it is sharper, faster, simpler to use and much safer.

Regularly sharpened plain edge knives on this machine are so sharp that they can slice bread better than a serrated bread knife, creating a really smooth slice with the minimum of effort.

Extensive testing within our knife laboratories indicate that the unit will give 8-12 years excellent sharpening in standard kitchen use, before the sharpening wheels need replacing.
