Special Series

Zirconia Ceramic Stone for Edge Pro

  Edge Pro form-factor stones are suitable for Edge Pro, Hapstone, TSProf and all Edge Pro compatible sharpeners



Zirconia Ceramic Stones are used for sharpening knives on Hapstone or Edge Pro knife sharpeners. Stones are mounted on high-quality aluminum blanks. Zirconia stones are made of Alumina-Zirconia ceramic with an extremely high hardness rating (over 9 Mohs) and estimated grit approximately 5000 JIS.

Alumina-Zirconia Ceramic scarcely wears over time. The material is used for manufacturing ceramic ball-bearings, dental crowns, and lapping plates for computer chips.

Zirconia Ceramic is preliminarily lapped and does not require lapping after purchase. Zirconia Ceramic stones should be used with oil as a lubricant (oleic acid, WD-40, refined olive oil).

Alumina-Zirconia has the density 4.00-4.05, compared to the standard Alumina density 3.70-3.75. The increased density gives the ability to make extra lapping if necessary.
