Many experts around the world proclaim that these are the best stones available for knives, chisels, tools and razors. They say this: "They are the best because they are attached to a glass backing, are easy to handle and store perfectly. Unlike other water stones, they do not require soaking before use and unlike other softer stones, they retain their flatness much longer than any stone we have used so far. This flatness is essential for wide blades such as the Japanese Nakiri. The abrasive abilities of the stones are faster and better than other types of stones, and we have found that the time we spend sharpening these stones has dramatically decreased, and the quality of the edge we can get has also improved. Without hesitation, we would recommend them to any sharpener who wants to improve their work.”
