The 2300 grit Resin Bond Diamond Matrix stone was formerly known as one of our diamond "polishing stones" for knives.

After experimenting with the resin bonded diamond stones in lower grits, we decided that we were going in introduce them as a whole new line of hand polishing stones in a league of their own.

If you're wanting a polished edge, and you find the polishing tapes to be too delicate, this 2300 grit polish stone is definitely the solution for you.

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 stones have a special feel of their own, and last an incredibly long time.

As the diamond polish 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.

    Just tried this stone on a Rex 45 Para 3 and it's awesome. Brought out the polish and left the edge ridiculously sharp. If you want to polish the edge on high hardness, high carbide steels the Edge Pro stones are the way to go.

    This 2300 grit Diamond Matrix Stone is fantastic! I purchase the entire new line of Diamond Matrix Stones. It leaves an awesome edge on the blade! I cannot recommend these new stones enough. IMO, this polishing stones produces a better edge then the 2000 grit polishing tape. And it is more durable!

    This polishing stone is fantastic! I have been sharpening with the Edge Pro now for 10 years. I have been using the polishing tapes during that time. These stones do not dish as easily and the stones and are a lot more durable then the tapes. Highly recomend!

    This stone gives a very good polish and a very, very sharp edge. I sharpen professionally using the Pro model. I want to share two tips I think are really helpful. As far as I know these are not widely known, the alcohol tip is something I found out more or less by accident. First, when the polishing stones get black with swarf from use, wipe them down with alcohol. It removes the black stuff like magic! Try it and you'll be amazed. I have asked Ben if the alcohol does damage to the stones, and he has confirmed that it does not. So don't sand them or level them just because they are getting black - just give them a good cleaning with alcohol on a rag after one or two knives. I use denatured alcohol. Thats tip one. If alcohol does not get them clean enough I use some water and kitchen scouring powder on a fingertip. Tip two: For a fast and sharp edge start with the 220 stone. Raise a burr and cut it off as usual. Make the bevels as even and perfect in appearance as you want them to be. Raise the angle just a bit and switch to the 2300 polishing stone. If the 220 is worn thinner you have to account for that as well when you change the angle, just raise the pivot post the same amount that the 220 is worn. Fine tune the angle so the 2300 is hitting the very edge. You want to hit the edge directly and a little towards the back of the bevel. The idea is to polish out the coarser scratches at the edge in a few passes. You don't want a second bevel but you want a bias towards the edge of the edge. If you color the edge with a marker you want to remove the marker at the edge but leave some faint marker at the back of the bevel towards the spine - that would be perfect. Start with a pull stroke, and go a little sideways each subsequent push-pull stroke. You will feel and hear the burr as a kind of gritty feeling as you sharpen. As the burr gets polished away this changes into a smoother feeling. When the whole side of the knife feels smooth flip the knife and begin again with a pull. Be careful as the burr will want to cut into your polishing stone if you push to hard, especially on stainless knives in my experience. Be gentle and go just a little sideways each stroke at a time and you'll be fine. Don't take wide sweeping sideways strokes until all the burr is gone. You'll know if the burr is gone by the feeling - gritty and its still there, smooth and it's gone. After all burr is gone, take sweeping strokes into the edge only just as when you are cutting the burr off with the coarser stones. Be careful at the tip as it also tends to gouge the polishing stone if one is not careful. It there are remnants of a burr you can remove them by drawing the edge through soft plastic, or stropping on clean, untreated leather. This two stone technique allows me to get razor edges very fast using only these two stones. So if you don't have the 2300 yet I can really recommend you get it. I prefer it to the polishing tapes when sharpening knives now that I have been using both for a while. The hard stone gives both audible and tactical feedback about the burr.I still think the tapes are better for hair shears.
