The HORL Kagami polishing stone isn't a sharpening stone that removes material, it's the finish that comes after. Where the diamond disc sets the edge and the ceramic side refines it, this ultra-fine disc smooths away the last microscopic irregularities. The result is a cutting edge with a mirror shine that's less prone to rolling over, so it feels sharp for longer.
What the HORL Kagami polishing stone does
A freshly sharpened edge is never completely smooth at the microscopic level. There's a fine burr left on it and the steel shows tiny ridges. That burr is exactly what breaks off first during cutting, which is why a knife can feel less willing to glide through a tomato after just a few days. Polishing afterwards removes that weak point before it announces itself. You notice it in how smoothly the knife slides through soft ingredients, and in the fact that you need to re-sharpen less often.
Who it's for
For anyone already working with a HORL sharpening roller who wants to add the final step. It's a refinement step, not a replacement for your regular sharpening: a dull or damaged knife goes on a coarser grit first. If you work with expensive Japanese knives or high-hardness steel, polishing is usually the difference between sharp and truly sharp.

How to work with the disc
Sharpen as usual first, and only switch to this disc afterwards. Roll with light pressure and keep the motion calm and even: with polishing, pressure doesn't help, but consistency does. A few strokes per side are enough. Wipe the knife off afterwards and check the edge on a sheet of paper.
Bill's tipPolish briefly and often rather than long and rarely. Two calm strokes per side after a cooking evening keep your knives at their best for months.
The complete sharpeners can be found under HORL knife sharpeners, such as the HORL 2 Pro sharpener. If repair work needs to happen first, take a look at the coarse diamond disc. Knives to practise on can be found in the knife collection.
