Gritomatic Ceramic Stone for Edge Pro

Description

Gritomatic Ceramic Sharpening Stones are used for sharpening knives on Hapstone, TSProf, and other Edge Pro compatible knife sharpeners. Gritomatic ceramic stones are made of 96% alumina ceramics with the addition of color-changing chemical components to improve its properties. The stone has an extremely high hardness rating and scarcely wears over time.

Gritomatic Ceramics is sintered from alumina grains with size 1 to 3 microns which finer than ultra-fine ceramic stones like Spyderco (3 microns average). But Gritomatic Ceramic is not ultra-fine stone. The stone is lapped in a special way to make it ultra-fast cutting stone in the middle grit range. You can progress to Gritomatic Ceramics directly from a 320-400 grit JIS, and it will create a uniform scratch pattern comparable to 1500-2000 JIS. You can use it as a finish (for toothy edge) or pre-finish stone (Spyderco UF is a good choice).

Gritomatic Ceramics stones have a very tight flatness tolerance that outperforms all other sintered ceramics stones on the market.

Gritomatic Ceramics stones can be additionally lapped with fine loose silicon carbide to make it ultra-fine. Because the structure is made from grains 1 to 3 microns, the lapped stone can reach 5000-6000 grit. (If you lap your stone, please be aware it would be difficult to reproduce the factory surface without special equipment.)

Gritomatic Ceramics stones can be used as a fine ceramic honing rod, i.e. not for sharpening but for daily maintenance of knives.

Gritomatic Ceramics stones do not require preparation after purchase. Gritomatic Ceramics should be used with WD-40 as a lubricant. If you don't have WD-40, use Ballistol or similar gun oil lubricant.
