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 1.5K stone is a great place to start when sharpening because of the toothy edge it will leave. This is one of the best stones to start on when beginning your sharpening progression. These stones measure 8.25” x 2.75” each.
The shapton pro 1500 hones very well and leaves a finer scratch pattren than the 1000. It is a little slower to get a burr but not much slower. After getting a sharp edge I can go to my 5000 grit stone without needing a coarser intermiate middle stone.
