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 them in your hand. The Matrix diamond stone sharpeners have a special feel of their own, and last an incredibly long time.

As the 450 grit sharpening stone wears, new diamond particles are exposed so the stone continues to cut at the same rate not losing any performance.

***Matrix Diamond stones are 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.

    Great for powder metallurgy steels

    I have always struggled to get my high end steel knives as sharp as cheaper knives with standard stones, and this is the answer to that problem. It is hard enough to cut the hard carbides in modern high end steels. For most, this 450 grit or the 950 grit are good choices for a finishing stone depending on the application.

    450 Diamond stone

    Great addition to the diamond stone line-up. Used yesterday on my Wustoff steak knives, followed by the 650. I have no need to get to a polished edge on these knives.
