The diamond Matrix line of knife sharpening stones was designed for the sharpening fanatics that insist on the best. Attention to detail and quality are immediately visible when you hold a 250 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"
***This diamond knife sharpener stone works great for sharpening ceramic knives.
* While we do all we can to reduce voids in the diamond blade sharpening stone we cannot guarantee all diamond grit sharpening stones will be free of them. These voids will not interrupt the sharpening performance.

These stones are amazing. I've had the Professional Edge Pro for 7+ years. The Diamond Matrix blow the old stones out of the water. While my skills have improved over time, the new stones reduce by maybe 80% the time it takes to put a new edge on a knife. I basically chucked all the old stones. I'm using the 250 grit to edge a knife, and 4000 grit to hone it. I may add a few interim diamond stones. But not much more is needed than that. Highly recommended, and totally worth the money.
These new Diamond Matrix Stones are amazing!! They are very durable and do not dish as easily, as the regular stones. IMO these stones put a better edge on a blade then the comparable grit in the original Aluminum Oxide Stones! I still use the 220 grit to set the bevel, but each stone after that are these new Diamond Matrix Stones. Fantastic Product Edge Pro!
