Thanks to pdTools for sending this stone for me to test out. Although my results were not stellar, I will revisit this in the coming days, and produce a follow up video. If you are interested in their products, the link is:

These are some direct quotes from my interactions with pdTools about their products:

Our company is one of the largest diamond tool manufacturers in the world. In addition, we were one of the first in the world to synthesize diamond. But unfortunately not everyone knows us as a manufacturer of diamond stones for knife sharpening. That's why we want to show our products to the world.
Price for such stone (as shown in my video) will be 128 USD (without delivery cost). Price will be the same for any grit.
Or we can use stone with smaller width (8" x 2"). Price for such plate will be 90 USD (without delivery cost).
To be honest, the most popular stones are those for sharpening knives by machine. This is why we do not have ready-made stones in stock. In general, we can produce any size and even label our stones in a special way. It depends on the customer's wishes. Which means if you want to sell our stones, we can add any inscription you want.
Regarding your questions:
Grit size available: from 60 grit up to 15,000 grit (from 250-212 um up to 0 up to 1 um); Grit size does not influence the price; 6"x1" mounted on a high-quality aluminum blank 3 mm or 4 mm / or without blank by request; Customization available; Brand name marking available.
About freehand sharpening - we are using 8" x 3" stones and have no blank. It`s full diamond stone. For such stones we prefer to use Metal bond.
We are producing them this way:
We prepare a mold with the desired dimensions of the product. We pour the diamond charge into this mold (this includes: diamond powder and bond. In our case it is a metal bond, which means it includes a whole list of different components. Copper, tin, etc.). Then all this is sintered at high temperature for 20-30 minutes. And then it is additionally processed. We mark the product, dress the diamond layer, make a chamfer, etc.
How is this different from ATOMA and other similar products. Sintering provides better retention of the diamond grit on the product. They just don't fall off as often when working.
If it is a galvanic (electroplated) method of applying the diamond grains to the product, then it is a different situation. In this process, there is no bonding, and the grains are attached to the body. Roughly speaking, the bond hides the grains and helps to sharpen the product, while in galvanizing (electroplated) the grains stick out and because of this they fall off faster. So sintering is better method of producing such things like diamond tools.
