Product Description

UltraSharp Diamond Sharpening Stones are the best value we've ever seen in a diamond sharpener. We've tested every diamond sharpening stone made and the Ultra Sharp performs as well or better than any of them. These extremely fast working diamond stone will quickly sharpen anything with a cutting edge including high carbon, stainless steel, and ceramic knives. The extra-fine 1200 grit surface puts a sharp edge on all knives and tools. Ultra Sharp Sharpeners are made of micronized monocrystalline diamonds which results in faster sharpening speeds and greater durability than fragmented polycrystalline diamonds. The diamonds are electroplated onto the metal plates. The key aspects of Ultra Sharp stones are the quality of the diamonds, the carefully graded particle size, and the dense, even distribution of the diamonds on the stones. The combination of these features makes the stones reliable, durable and an exceptional value. You won't be disappointed!
