Product Details

An interchangeable disc that affixes to the roller of HORL 2 or HORL 2 Pro knife sharpeners (not the HORL 2 Cruise), this standard coarse diamond-coated disc is a replacement part. It is best suited to sharpening blunt Western or Japanese knives, and should be followed by honing to realign the edge. To use, simply unscrew an existing disc from a compatible HORL 2 roller, replace it with this one, and sharpen. The compact size makes it easy to store. Please note that the first few times the diamond grinding side is used, excess diamond particles may be noticeably heard peeling off. After a few applications, the grinding sound becomes quieter and the grinding surface stabilises. 

Please note: HORL products can only be shipped within the UK

Why we love it

'The HORL 2 is quick, neat, and effective. While whetstones take time and practice to master, the HORL 2 does not. It’s like having the ease, speed and definition of a pull-through sharpener, but the versatility and relative gentleness of a whetstone.'

Specifications & Care

  • Clean with an eraser to remove dust
  • Alternatively, the diamond disc can be unscrewed and thoroughly cleaned with a little detergent, warm water and a brush

About The Brand


Timo and Otmar Horl, the father-and-son duo behind HORL 1993 had a singular vision: bring professional standards of knife sharpening to the home cook, simplified. What began at a home cellar is now a fully-staffed workshop in Germany’s Black Forest where every aspect of the manufacturing process is done locally, from steel melding to laser engraving.
