Designed to the same exacting standards as our larger commercial machines, the CATRAHONE Diamond Power sharpener provides the home and very light duty commercial user with high quality sharpening to factory levels of sharpness.

Using  a simple yet effective principle the unit provides the user with three operating slots:

  • for restoration of very worn blades that need cutting edge reformation
  • for every day sharpening of most blades
  • for that final super smooth hone after using slots 1 and 2

By use of the special cool sharpening technology, the sharpener does not need water cooling and yet does not over heat the cutting edge, unlike other dry sharpeners, providing you with the maximum edge life for you blades, up to 100% more life than some other electric power sharpeners. Compared to a sharpening steel is is sharper, faster, simpler to use and much safer.

The optimum cutting geometry is permanently set at 34° and won’t change with use, thereby not requiring any adjustment. Regularly sharpened plain edge knives on this machine are so sharp that they can slice bread better than a serrated or scalloped bread knife, leaving virtually no crumbs, creating a really smooth slice with the minimum of effort.

Powered by a plug in power supply (universal voltage with internationally adaptable plug, we will supply the correct one based on your chosen shipping destination).) the sharpener runs on a safe 24V DC current which means there is no risk of electric shock from using the unit.

We offer a money back guarantee if you buy from our online shop if for any reason you dont like it.

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