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 15k 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.
Very nice stone. It’s about half as thick as my Chosera stones,but very nice nonetheless. The stone is nice and hard and pulls metal instantly. The splash-and-go non-soaking quality is great. This 15K might not be as legendary as the Chosera 10K,but its a fraction of the price and a great finishing block for sure. I have a combo of Chosera and and Sharpton Pros. 400,800,1000,3000,5000 are Chosera and the 220,8000 and 15000 are Sharpton. I’d highly recommend either brand,but do prefer the "feel" of the Chosera. If you are looking north of 5K then these Pros are your best bet!
Note: Although I do used these on kitchen blades,I used them primarily to reprofile and recondition my outdoor scandi and convex ground knives.
All in all an excellent stone. Once lapped,it does not dish quickly,cuts very fast and leaves an excellent edge.
