Diamond & CBN-stones from Ukraine have some difficulties:
*****
Since the PDTools (UKRAINE) factory is experiencing difficulties of war, the plant reserves the right not to paint aluminum backing plates for sharpening stones, so some sharpening stones from Ukraine may not be painted and may be differ from the photos, but HOWEVER THIS DOES NOT AFFECT THE PERFORMANCE CHARACTERISTICS OF THEM OF ABRASIVE MATERIAL inside THE SHARPENING STONES!
Attention:
The guarantee of the factory products from Poltava city PDTools (UKRAINE) is their gluing on a 4 mm backing plates in the factory way - for other sharpening bars, glued on a 3 mm backing plates (Hapstone, Gritomatic etc.), the factory DOES NOT BEAR RESPONSIBILITY AND DOES NOT GIVE a factory guarantee for those sharpening stones:
Attention:
Warning: PDTools trademark on the back of the aluminum's backing blanks 5/32” = 4 mm (See Attached picture from their booklet) high, can guarantee that you have purchased the PJSC Poltava Diamond Tools Superabrasives factory’s product for the American market from the Authorized dealer in North America (See Attached photo of our certificate)!

! Mr. Efim
Dreer (Canada) - 37 years on the sharpening field, creator of the Flip-in-Sharp
rotary mechanism, which allows you to sharpen a knife without removing it from
the clamps, said (See the picture): - Yes, guys! Now, in nowadays, CBN stones are the best in the
world! Of course, it’s a pity - the era of natural stones like Arkansas,
Washite, Lynn Idwall, etc. has passed. Yes, CBN stones do not require frequent
leveling and I flatten them no more than once every year and a half... ! :

Loveless) wrote me response under this video:
Mr. Levitt
Now that I've had a chance to really
try these stones, I'm very impressed! I have a lot of diamond stones here.
Simple plated stones, Venev Diamond Stones that are a nonmetallic binder along
with Jande and Columbia Gorge. Nothing, and I mean nothing cuts like these
stones. Fast, but the finish they leave on the blade is crisp like I've
never seen before. Even the coarser grits such as the 550 and 650 grits shave
well, smooth in paper slicing but have an aggressive nature that must be felt
to believe. So aggressive in fact that care must be taken around the edges. Not
for the careless user!
I will be ordering more of these
stones. The ones shown here are for fixed angle sharpeners, but I do need to
pick up a couple of bench stones. It's on the to do list!
I can't thank you enough for pepping
these stones for me. I already have many hours using them on from D-2, 154-cpm,
to M-4 and S90V. These stones are like the Honey Badger. They don't care!
Nothing is too tough for the. :<)

Knowledge: CBN vs Diamonds - Whetstone built to do the job. Everything you need
to know - https://youtu.be/8DD2yQj7K8E - In video CBN -
stone bonded by resin and we sell MUCH BETTER - these stones are bonded by a
copper-tin metal. ONLY the PDT factory (Ukraine, Poltava) has this technology
in the World!
Tips:
Question from: marbalie-0 (148)
Are these stones resin bonded or electroplated? Not really seeing specifics.
Answer:
These stones are bonded by a copper-tin metal. This distinguishes them from Chinese (bonded by electroplated) and from European ones (on a resin bond). That is, cubic nitride boride (CBN) is added to boiling copper-tin lava and it is "baked" in a metal base. This technology is available ONLY at the Poltava Diamond Tools factory (!), which makes the sharpening process with these types of stones the strongest and most durable in the WORLD - you can sharpen up to 77,000 knives (depending on the Grit size) with one bar!
For Example:
A lot of people make mistake between CBN-stones and Diamond:
