HORL HORL3 Whetstone S5-HO3-P - Extra Fine

The HORL3 Whetstone – Extra Fine is a finishing-stage sharpening disc designed to push edge refinement beyond the standard diamond and ceramic setup in the HORL system. Made from corundum (aluminum oxide), it is used after the fine whetstone stage to further reduce scratch patterns and produce an exceptionally smooth, low-drag cutting edge. Unlike traditional water stones, it is designed for dry use, simplifying the sharpening process while still delivering high-level refinement. The disc mounts via the HORL Quick Lock system, allowing fast, tool-free changes, and is compatible with the HORL3 and HORL3 Pro platforms (not HORL2 or HORL3 Cruise). Functionally, it serves as a pre-polishing step, ideal for users looking to maximize sharpness and edge consistency before stropping or moving to ultra-fine options like the Kagami.
