This DMT Dia-Sharp D8XX Diamond Plate measures 8" x 3" and has a grit of 120. This plate is most frequently used for flattening stones and for quick removal of steel when you need to repair a knife. Here is a great video that demonstrates the use of this plate for stone flattening.
I use this to lap my courser stones (1000 grit and below). It is the only stone fixer I have used that does not get damaged flattening 220grit stones. Much cheaper and more versatile than the Shapton Diamond Lapping Plate (which would be ruined lapping a 220grit stone) although not as perfectly flat I cannot tell the difference.

love it for smoothing stones,in addition,i took a five year old mac bread knife,grinded the serrations down with this,then sharpened with my choseras and gave a young cook a slicing knife so he didn’t mess up my proteins. two birds,one stone,no pun intended.

Great product. Works well on all of my stones,a little rough for 5k stones and up,but overall great to work with.

I purchased this for flattening stones after watching the videos on the website. It was used to flatten Shapton 1K and 6K stones. It worked perfectly following Mark’s instructions.

Fantastic. I bought this item to repair a knife with a broken tip. With the help of the tutorial video,I went to work and I was very surprised how fast I came to result. I followed advices and a new knife was born. I also had a damaged water stone,and again,problem solved in minutes. Perfect to flatten stones. Highly recommended product.

It’s a fine product that I have had little chance to use.

A little pricey but the easiest way to level your water stones- which is what I primarily use it for.
