Shapton stones are designed to be harder, faster cutting, and denser than any other ceramic water stone on the market. Because they remove material quickly, the time required to hold an angle on the stone is reduced, making free hand sharpening much easier. Shapton water stones are made with finely-graded ceramic cutting media, which wears much more slowly than aluminum oxide and silicon carbide commonly found in other man-made water stones. These are splash-and-go stones, so no soaking is required. This results in a similar thickness of sharpening material lasting much longer. The 16k stone will achieve a nice mirror finish to any blade edge. A great stone for finishing straight razors, it will refine edges beyond what many would think possible. These stones measure 8.25” x 2.75” each.
