Idahone 9" V-Type Replacement Ceramic Rod - Fine Grit

Restore the Factory Polished Edge to Your Idahone V-Type System


Precision-engineered 9-inch high-alumina ceramic rods designed for the final honing stage of your CS-4 or CS-24 sharpening base.


When your kitchen knives lose that effortless 'bite' through tomato skins or delicate proteins, the issue is often a misaligned edge rather than a truly dull blade. Replacing worn or broken rods with the genuine Idahone Fine Ceramic Rod restores the high-performance finishing touch your cutlery requires. During hands-on testing, this rod provides a distinct tactile feedback—a smooth, controlled 'zip' as the steel passes over the ceramic. Unlike metallic steels that merely realign the edge, this high-alumina ceramic lightly hones, removing microscopic amounts of metal to reveal a clean, polished apex.


Measuring exactly 9 inches in length with a 5/16-inch diameter, these rods are manufactured in the United States to strict tolerances. The 'Fine' grit is approximately equivalent to a 1200-1500 grit waterstone, making it the ideal secondary stage after using medium-grit rods. When inserted into your CS-4 or CS-24 wood block, the rod fits securely without wobble, ensuring the consistent 15-degree or 22-degree angles required for professional edge geometry. This isn't a generic substitute; it is the exact abrasive component that established Idahone as a staple in professional butcher shops and commercial kitchens for over 40 years.
