This Ozaki tenjyo strata asagi type stone (slightly green) is perfect with a wide variety of knives, and tools. It is fast-cutting and excels with hard steels.  
 
I feel it is best as either a fine knife stone, or for tools chisels. It can also be used as a prep stone for razors. This is a very homogenous stone. This Ozaki has a table top flat back, 3 square corners as seen in the photos and it will fit into most stone holder, or you can use it on a table top. I will back up its quality with a money-back guarantee minus the return shipping. 
 
The top surface and all of my stones have been flattened, and the side edges of the top surface have been beveled, This stone comes with an appropriately sized and tested tomonagura slurry stone. The missing corners is reflected in the retail price.
