Attention:
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 - he is the Father of the TSProf, Hapstone, Efim-2 and etc. sharpening systems, 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... ! :

! Mr. Michael Lovett (a friend & the partner of Bob Loveless) wrote me his 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 an 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 has to 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 too 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. :<)

Cubic Boron Nitride (CBN) is the Micro powder Super abrasive.
Knife 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:

Additionally:
Diamond contains carbon, and all steel contains carbon. That is, when you are sharpening with diamonds, carbon sharpens carbon, which is not the best way to process steel. Only CBN (Cubic Boron Nitride) does not contain carbon and it is close to diamonds in hardness! Thus, there is no MATERIAL BETTER than CBN yet 😊!
P.S.
These bars will be inherited by your grandchildren, for sure - we have NO DOUBT about this, and IN ADDITION no lubricants or coolants are required during the sharpening - your desktop will always be clean. 😊

😊 Cubic Boron Nitride (CBN) is second only to diamond in hardness, BUT two times that of diamond in high temperature resistance, four times that of traditional abrasive in wear resistance, and have extraordinary thermal conductivity. It is designed for fine grinding and polishing in a variety of demanding surface finishing, such as metal bond grinding wheels, resin bond grinding wheels, vitrified bond wheels and electroplated products.

To be, or not to be, that is the question:
(From Hamlet, spoken by Hamlet)
Do you wanna “to be, or not to be” on the Top Level?
Do you wanna “to be, or not to be” on the Supreme Union?
Do you wanna “to be, or not to be” the BEST?
If you wanna TO BE, WE ARE
INTRODUCING TO YOU - what do you WANT:
THE NEW ERA ON the sharpening’s
community coming, and IT IS COMING NOW - ELBOR's (CBN) – as the
artificial diamond!
👑We Are an Official Representative PrJSC PDT® (Ukraine)
in the USA👑
THE OFFICIAL PRODUCT FROM PrJSC PDT® IN SOUTH AND NORTH AMERICA
👑 Lifetime Bonded Clutch Warranty
from PrJSC PDT® 👑
So,
Put aside your Arkansas stones -
let them "rest",
Put your Naniwa’s stone into some
water before it starts to work - let them "drown" in the water &
"suck" something,
Give your Boraide’s sharpening
stones away to your friends - let them "remember” you...
And
GO TO MOVE
ON CBN (ELBOR / BORAZON) THAT GIVE YOU OPPORTUNITY:
v No fear of getting cancer - no
phenol-formaldehyde bonds, only copper-tin (soft brass) bond between Elbor (CBN)
grains.
v No parasitic scratches on the
cutting edge on your knives like natural diamond did - the artificial Elbor (CBN)’s
crystal is "grown" in the laboratory under the control of engineers
and has smooth edges.
v No water or oil as lubricants, and,
as a result, no dirt on the worktable when you will be sharpening your knives –
Elbor (CBN) works dry.
v There is no need to prepare the
sharpening stones for work - just "take it" and "work
with".
v No purchases of new stones after
one year of operation - at least 17,300 sharpened knives are a factory
guarantee (applies to stones with a grain size of 1,000 Grit and above).
v No headaches with the return of
goods - send to the factory a passport with the serial number on the sharpening
bar and receive a new sharpening stone without complain (in the absence of
signs of strong mechanical impact or deliberate damage).
v Lifetime factory warranty until the
grinding mass disappears in the stone (it is 1,5 mm)
v
So, ARE YOU “IN’ or “OUT”?
v
If you are “IN”, then I will remind you of the story that
the USSR had three main pillars of industry that you probably know about:
1. Kalashnikov assault
rifle - AK-47
2. The first Korolev rocket
in space with the first SPUTNIK and then with the first
cosmonaut YURI GAGARIN.
3. The artificial diamonds –
ELBOR (CBN).
Dear friend,
You may remember the first two, but of course you did not know
about Elbor (CBN).
So, Elbor (CBN) is a secret development of Soviet
scientists (In the USSR, cubic boron nitride was first synthesized in 1960 at
the Institute for High Pressure Physics of the Academy of Sciences under the
leadership of academician L.F. Vereshchagin and was named Elbor (Leningrad
Borazon (CBN – Cubic Boron Nitride – THE USA
ABBREVIATION). Since 1965, Elbor (CBN) has been synthesized on an
industrial scale using the technology of the “Ilyich Abrasive Plant” (City of
St. Petersburg – before named Leningrad city), which became available to the
whole world after Perestroika. The Poltava Diamond Tools Factory (Ukraine) sold
this technology to Holland in 1993, and now the Elbor’s artificial diamond
produced in Holland have become the basis to manufacture the
"PREMIUM" series sharpening stones in Poltava Diamond Tools Factory (BEWARE OF COUNTERFEIT FROM ASIA) with the
following characteristics:
Description
Metallic CBN Sharpening Stones are used for sharpening knives using Edge Pro, Ruixin,
Hapstone, TSPROF etc. sharpeners. CBN (Cubic Boron Nitride) is the
second-hardest material after diamond. Metallic CBN stones utilize copper-tin
alloy bonding for high endurance and low wearing rate.
Metallic CBN Stones consists of a 3,0 mm
thick metal plate (making by one piece of the 1,5 mm CBN-bearing + the 1,5 mm
copper-tin alloy) mounted on a 4,0 mm a high-quality aluminum blank.
CBN's qualities include high levels of high
hardness, strength, abrasion resistance, and thermal and chemical resistance.
These characteristics exceed the values of synthetic diamonds and conventional
abrasives such as silicon carbide and aluminum oxide. CBN’s high thermal
stability and chemical resistance make it suitable for sharpening in conditions
where synthetic diamonds are not normally employed.
CBN offers excellent performance in
sharpening knives of any steel. Due to its high resistance specs, CBN can be
used dry without lubricant. This makes CBN the cleanest of the available
sharpening stones.
How to use
Metallic CBN can be used without
lubricants.
Metallic CBN stones may have
tone imperfections. Metallic CBN may become darker over time due to
natural metal oxidizing, it does not affect the sharpening.
Metallic CBN stones do not require any preparations.
Q & A
· CBN sounds like a wonderful abrasive that is far better than
anything else on the market. So, what's the catch?
CBN provides
high performance, sharpens any steel, has low wear rate and low stress, does
not create mess, and does not leave unwanted grooves. The price tag is
expensive. However, remember that the number of knives guaranteed by
the manufacturer that you will be sharpening with CBN is 7300 knives (applies to stones with a grain size of 1,000 Grit and above), and for example, you will sharpen 1217 knives with Boride
(information obtained in practice from Mr. Efim Dreer (Canada) - professional
sharpeners and inventor of the “Efim-5” sharpening system). That is, you buy
CBN once AND FOR THE WHOLE LIFE ... even your grandchildren will use these CBN
100% for sure, if they decide to sharpen knives!
· Can I sharpen ceramic knives with CBN?
Theoretically,
yes. However, sharpening ceramic knives is technically difficult and uneconomical
in most cases. CBN stones can cause microchipping when used on ceramics.
Consider purchasing a new ceramic knife instead of sharpening it.
· What is PDT means, it printed on
the sharpening blanks?
The PDT is an
abbreviation for the name of the "Poltava Diamond Tools" plant in
Ukraine - the manufacturer of these sharpening blanks made from CBN: https://youtu.be/lOcRcQfGYMk .

CBN sharpening stones
An analog of diamond bars that
allow you to get a mirror edge are bars of boron nitride (CBN). Cubic boron
nitride is a synthetic material that is close to diamond in hardness but has
higher heat resistance. It is a chemical compound of two elements — boron
(43.6%) and nitrogen (56.4%) and has a crystal lattice with almost the same
structure and parameters as diamond. CBN bars are produced on metal bonds,
which are based on copper and tin compounds, as well as on an organic bond
(Bakelite) based on phenol-formaldehyde resin (We do not recommend this
Bakelite bond as its use increases the likelihood of cancer and is not
recommended for sale in the state of California). At the same time, it should
be noted that CBN bars on a metal bond, despite their hardness, are able to
give the secondary bevel a clean mirror surface. However, as with diamond
polishing, this will take quite a long time. The 3/2 μm (F 5`000) bar already
gives excellent results, and the 2/1 μm (F 10`000) bar guarantees a clean and
even mirror.
Metallic CBN can be used without
lubricants.
Metallic CBN stones may have tone
imperfections. Metallic CBN may become darker over time due to natural metal
oxidizing, it does not affect the sharpening.
Metallic CBN stones do not require any preparations.
