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… ! :https://youtu.be/B3M8Xn-FXiA?si=PkROKD0h7Hn2N-Hi ! Mr. Michael Lovett (a friend & the partner of Bob Loveless) wrote me his response under this video:Mr. LevittNow 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. :<)KnifeMaker/Mike/Retired after over 47+ years in the Craft. ! : ! Mr. MICHAIL LOVETT from the TAXES (USA) - See the pictures: subhilt9 (141) US $ 64.04 !

Mr. MICHAIL LOVETT from the TAXES (USA) - See the pictures: subhilt9 (141) US $ 64.04 ! We Are Selling the Original PDTools Product in North America: (Guys, Beware of Scammers! https://www.youtube.com/watch?v=r63OK8DQyCg, https://youtu.be/qtsX5jxz6g8. - Example. Not for selling. The actual product sees on the pictures on eBay. This knife was sharpening by PDTools CBN-stone (video from some our buyer) - https://www.youtube.com/shorts/DtGegwq2hNw.) Because Of We Are the Official Dealer of the PDT-Factory, Ukraine in North and South America (See Attached Photos).From the previous Buyer from the USA: bobilliam (41) US $ 340.00 Used these stones a couple times so far, very impressed. Very fast cutting with no loading or glazing like resin bonded stones and surprisingly very good feedback when you're off angle. Nothing like a resin bond stone or a electroplated stone. The edge the 20/14 stone leaves after stropping on 14 micron cbn is exactly what I was looking for in my k390/maxamet/etc. Might need to try some higher grits in the future. Highly recommended!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! Material & abrasive: CBN - cubic boron nitride. It has the best cost/productivity ratio for processing of STEELS, comparing to diamond and cheaper stones. CBN stones are similar in qualities to Japanese wet stones, but have ten times longer working life. CBN is a generic name, there are also other names of this material, depending on manufacturer: borazon, elbor, cubonite. Metal bond Will last forever, although nothing is forever. Concentration 100%.Do not waste your money on cheaper stones with lower/unknown concentrations. PreparationStones with grits finer 3 microns either require preparation on cast iron plates, or they will be self-polished after sharpening of 30-50 knives. Then they will be of gold color and work well. Use and cleaning (unclogging)Use any comfortable oil (baby, olive..) to prevent glazing. If glazed - clean (unclog) with alcohol and toothbrush. Maintenance is only needed every year or two to flatten stone or "open up" abrasive grains. In 1-2 years you may need to flatten stone, on the glass with silicon oxide powder or iron oxide - grinding is carried out using powder of the same grit as the will be leveled sharpening stone (!). 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: FeedBaсkFrom the previous Buyer from the USA: innuendos (1117) US $ 515.00 AMAZING stones - they remove steel fast, with minimal effort. I like the fact that the abrasive is bonded in metal (copper + tin) and will resist dishing a lot better than resin (Note from seller: ONLY PDTools, Ukraine CAN PRODUCE the CBN-stone IN THE COPPER+TIN BOILING LAVA IN THE WORLD IN NOWADAY! 😊). I have sharpened 3 knives and for D2 steel I only needed up to the 650 Grit to produce a razor's edge - google "PDT CBN Stones" (Note from seller: PDTools, Ukraine CBN-stone😊) and watch video or search title at YouTube. These left my cheaper diamond stones in the dust. This seller is very knowledgeable and stands behind his products. A great seller!The EXPERT Set / 25mm – CBN sharpen/honing stone Edge Pro Ruixin TSPROF Hapstone (# 175387035682)FeedBaсkFrom the previous Buyer from the USA: reno_raines99_5 (84) US $ 515.00 I've had these for a week now and they are the best diamond stones (Note from seller: This is the CBN-stone😊) I have tried. They are expensive and may not be for everyone but if you are someone who does a lot of sharpening and doesn't want to keep replacing the diamond stones or just wants the best product then this is for you.The EXPERT Set / 25mm – CBN sharpen/honing stone Edge Pro Ruixin TSPROF Hapstone (#175387035682) 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. 😊 https://youtu.be/qtsX5jxz6g8 (Example FOR EUROPE MARKET. Not for selling) 😊 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.😊 Only we – PrJSC Poltava Diamond Tools, Ukraine – makes CBN by metallic (Copper + Tin) bonded in the sharpening stonesF 550 grit (40/28 μm) CBN sharpening/honing stones 150-17-7-3 to Edge Pro Ruixin TSPROF Hapstone (see on 2:09 minutes on video: https://youtu.be/RAy8olk8cMo)About this item:· 550 grit – U.S. Standard ANSI· CBN sharpening stones, Poltava, working surface: · 5 29/32" x 47/64" x 1/8"· (150 x 17 x 3 mm) · Length: 150 mm = 5.91 inches · Width: 17 mm = 0.67 inches · Thickness: 3 mm = 0.12 inches · REMEMBER – It was mounted to aluminum plate: 160x17x4 mm · Material: CBN - cubic boron nitride.

Kalashnikov assault rifle - AK-472. 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: DescriptionMetallic 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 useMetallic 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 .

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.GritMicronPurpose📈80 grit200/165 μmOptional/Alternative📈160 grit125/100 μm🔢Recommended as #1📈320 grit60/40 μmOptional/Alternative📈460 grit40/28 μm🔢Recommended as #2📈650 grit28/20 μmOptional/Alternative📈1500 grit14/10 μm🔢Recommended as #3📈3000 grit7/5 μmOptional/Alternative📈4000 grit5/3 μm🔢Recommended as #4📈5000 grit3/2 μmOptional/Alternative📈10000 grit2/1 μm🔢Recommended as #5📈15000 grit1/0 μmOptional/Alternative
