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 corundum stone disc is available in #3000 or #6000 grit for achieving higher degrees of sharpness on Western or Japanese blades. To use, simply unscrew an existing disc on an applicable HORL 2 sharpener and replace with this one. The #3000 grit provides an even finer edge than the standard ceramic honing disc, and the #6000 goes even finer than that. Please ensure your knife is already sharpened and honed before using the corundum stone, as it is meant to refine an edge of a sharp blade rather than sharpen. The compact size, in comparison to a high-grit whetstone, makes it easy to store. 

These corundum stones are available as a set, with the addition of a polishing strop, here.

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.'

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.
