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. This results in a similar thickness of sharpening material lasting much longer. The 1K stone is a great place to start when sharpening because of the toothy edge it will leave. The 4K is the perfect progression after the 1K for the refining of the edge it will achieve. The 8k stone will further polish and refine the edge leaving an almost mirror finish. The 16k stone will take your edge to a nice polish and is also a great stone for finishing straight razors. These are splash-and-go stones so no waiting while they soak making them exceptional for students and professionals alike. These stones measure 8.25” x 2.75” each.
Some years ago,a Japanese friend told me that I needed step-wise stones for really sharp knives. That got me started. When I read about the Shapton stones,I got really excited about this set. My friend said that the 16,000 was unnecessary,but when I polished my Japanese knives on it after using the others,they were amazing. My yanagiba looked like a mirror,and cuts fish as though going through liquid. My nakiri slices carrots more smoothly than I could imagine possible,making katsuramuki and sengiri amazingly easy.
