From the previous Buyer 😊from Singapore😊: denebman (17) US $ 283.00 This is the first time I have used metallic CBN stone. Sharpened a few knives in CPM 3V, 154 CPM, carbon steel and Sandvik's (14c28n). The overall feedback is excellent, the stone just kept eating up steel without losing any aggressiveness. Reprofiling is a breeze. I will come back and order a full-sized set (25mm) in the near future! The BASIC Set / 17mm: CBN-stone Apex Edge Pro / Ganzo / Ruixin / TSPROF Hapstone (# 175506636648) ! 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... ! : https://youtu.be/B3M8Xn-FXiA?si=PkROKD0h7Hn2N-Hi ! Mr. Michel Lovett (a friend & the partner of Bob 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. :<) 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 !

ONLY the PDT factory (Ukraine, Poltava) has this technology in the World! 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!The EXPERT Set / 25mm – CBN sharpen/honing stone Edge Pro Ruixin TSPROF Hapstone (# 354426287733)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.
