At the time of writing, this 8 inch, single-sided stone is the only Extra-Extra-Fine (3 micron, or 8000 grit, according to DMT's product pages) DiaSharp continuous surface diamond hone available from DMT, making it the finest grit stone in their line. It is designed for finish sharpening of cutting edges, which I have found that it does very well on woodworking tools, knives, and swords. I would warn waterstone users not to use any DMT product for dressing their waterstones. According to both DMT, and several horror stories in sharpening forums, the nickel substrate of the diamond hones can be eaten away by waterstone slurry, causing the diamonds to be loosened and removed, permanently ruining the diamond hone. This is probably true of all other single-abrasive-layer diamond hones on the market as well. If you are looking for a waterstone flattener, buy something specifically designed for it. I mention this because this type of stone might initially look ideal for flattening other stones, but won't survive that use.Read full review

I've only had this for a couple of days so far, but it appears to do a very good job of refining edges on knives & shears. It is a nice thick and heavy piece of metal, which is good. I wouldn't say it's "good value" because it is quite expensive, but I would say it is probably worth what I paid. Time will tell as I want it to last for many years.

This stone was delivered ahead of time. I have used it to rough edge 9 knives since I got it. It works fantastic.

It enables me to put a really fine edge on a blade. I can use it on any flat blade that does not have a concave curve to the cutting edge.

Sharpens quickly with less mess than waterstones. Will also outlast waterstones.
