The diamond Matrix line was designed for the sharpening fanatics that insist on the best. Attention to detail and quality are immediately visible when you hold a 300 grit sharpening stone in your hand. The Matrix diamond blade sharpener stones have a special feel of their own, and last an incredibly long time.
As the stone wears, new diamond particles are exposed so the stone continues to cut at the same rate not losing any performance.
***Ideal for the modern "super steels"
***Works great for sharpening ceramic knives
* While we do all we can to reduce voids in the stone we cannot guarantee all stones will be free of them. These voids will not interrupt the sharpening performance.
