Excellent diamond blade dressing stone21 May 2017 - Published on Amazon.com
This works as a nice dressing stone for diamond blade saws. Plus at this price point it's a lot less expensive than items labeled specifically as diamond dressing stones. The stone is silicon carbide (SiC) although that's not clear in the ads and the box labeled it as silicon oxide (which it's not). The SiC stone is 240 grit on one side and 320 grit on the other. The dimensions in the specifications are accurate, other stones seem to short you on the dimensions. Overall, this is well worth it for dressing your diamond saw blades.

Standard abrasive block.7 December 2017 - Published on Amazon.com
Does what it is intended to do. The grit (240/320) appears to be accurate by the description. The block arrived intact with just a few nicks and chips on the corners and edges and the work faces are flat and true. The package label however describes the material as silicon oxide which is just plain glass. The material is gray instead of the traditional green silicon carbide (part of the item description) which is used for manual dressing of tungsten carbide cutting tools such as lathe tooling. If it holds up to manual dressing of tungsten carbide lathe points then it was worth the cost.
Pretty good24 August 2013 - Published on Amazon.com
This wet stone is recommended to be used with oil, but I'm using water so I may not be getting the full effects of it. Regardless it's still a great product. It's allowed me to grind down and reshape blades, and even different steel items, on the rougher side and the smoother one has allowed me to sharpen the blades pretty well, but not to the point where you can shave with it as it's nowhere near fine enough. The grit will give you a nice hone that would be more than enough for everyday needs.

Great delivery, the actual product was delivered in good ...6 July 2014 - Published on Amazon.com
Great delivery, the actual product was delivered in good shape. The instructions say to immerse for about a minute to fill it and that this stone is used with oil as a lubricant. Just looking at the stone from all four sides of the two grits it's not perfectly even and appears to be more of the 240.
