HORL® Kagami - Ultra-Fine
- Ultra-fine finish for a mirror-smooth cutting edge
- Swappable on the HORL sharpening roller
- Cutting edge stays noticeably sharper for longer
A freshly sharpened knife feels sharp, but at a microscopic level there is still a fine burr on the edge. That is exactly the bit that breaks off first, which is why a knife sometimes glides less smoothly through a tomato after just a few days. The HORL Kagami polishing stone smooths out those last unevenness, as a finishing step after your regular sharpening.
For anyone already working with a HORL sharpening roller
This is not a replacement for sharpening, but the step after it: first the diamond disc to set the edge, then ceramic to refine it, and finally this ultra fine disc to make the edge truly mirror smooth. If you work with an expensive Japanese knife or highly hardened steel, this is often the difference between sharp and an edge that still cuts just as well at the end of an evening at the table as it did at the start.
- Ultra fine finish for a mirror smooth edge
- Interchangeable on the HORL sharpening roller
- Edge stays noticeably sharp for longer
- Meant as the final step, not the first sharpening pass
Use
Roll with light pressure and a calm, even motion, a few passes per side is enough. Two calm passes after a cooking evening keep your knives at level for months.
This is a single disc: you can find the complete sharpener at HORL knife sharpeners, and the knife itself at kitchen knives.
