Duurzame CBN-stenen met soepele snijwerking voor het slijpen van moderne hoogharde staalsoorten en keramische messen.
Snijden
Kubisch boornitride zorgt voor een efficiënte staalverwijdering terwijl het soepele en gecontroleerde snijgedrag tijdens het slijpen behouden blijft.
Feedback
De metaal-organische verbinding combineert de duurzaamheid van metaalverbindingen met een soepeler slijpgevoel en een meer voorspelbare randcontrole.
Duurzaamheid

Sharpened a Kunwu Excalibur in Vanax, no strop used just straight off the stone 👌 Absolutely insane edge! Gives a very, very good mirror but it keeps the bite you’re looking for!
Store owner replied: Amazing results, Steffen! We're thrilled the Premium CBN stone delivered such a sharp, mirror-finished edge while keeping that perfect bite. Thanks for sharing your experience!
What a beast for reprofiling! By far the best 80 grit stones for fast removal of ANY steel!
Store owner replied: That's awesome to hear, Steffen! We're glad the 80 grit Premium CBN stone makes reprofiling so fast and effective. Thanks for the great feedback!
By far the best 150 grit stone I’ve yet to try out! What an amazing stone to work with, just keeps going man! I used Hapstones own magic oil, tried with a few other brands of oil, but I surely prefer the magic oil. Makes the stones work like magic 👌
Store owner replied: Fantastic to hear the 150 grit Premium CBN stone has impressed you so much, Steffen! We're glad it's performing so well with our Magic Oil. Thanks for your continued support!
Very consistent. Please note that I have removed the silver coating via initial flattening. This exposes the bronze/copper underneath which is in my view more consistent and faster in abrasion
Store owner replied: Thank you, Benjamin! Glad to hear you’re getting such consistent and fast results — appreciate you sharing your approach!
Awesome stones. Only used them on about 5 knifes, but performance is great and it feels like they gonna last a long time. Much better than the ones that came with my sharpener of another brand. Highly recommended!
Store owner replied: Thank you, Johan! Glad to hear the stones are performing great for you. Thanks for the recommendation!

I'm sharpening already a long time by hand on many different kind of stones, I wanted to try something different so I decided to buy the Hapstone RS with premium CBN stones. It's a really good system, very consistent. The premium CBN stones are really insane, I bought the 80, 150, 400 and 800 grit. I personally prefer aggressive edges on all my knives so I rarely go above 600 grit, if you really want insane sharp edges the CBN premium is your choice. You easily can get a double hair whittling edge with only the 80 and 150 grit and stropping with a 0.1 micron CBN compound as long if you are very keen on burr removal, which is super easy on the Hapstone RS. The premium CBN stones are easily among the best stones on the market.
Store owner replied: Thank you, Ramoël! Great to hear you’re enjoying the RS system and the performance of the Premium CBN stones — sounds like you’re achieving some impressive edges!
Good
Store owner replied: Thanks, Viktor! Glad you’re happy with it
As mentioned in my 800 & 2k reviews, these stones differ from what I'm accustomed to. They feel excellent—hard, consistent, and precise—leaving a shallow scratch pattern. I strongly recommend removing the silver coating and conditioning the surface with a nagura stone periodically to keep the surface open. The 5k stone requires additional consideration. Many polishing stones leave highly reflective, clean surfaces marred by intermittent random scratches. The CBN 5k initially suffered from this issue. If you want a "good enough" polish with a refined edge, simply removing the silver coating suffices—you'll be satisfied. However, if you demand mirror polish perfection, those scratches become unacceptable. After troubleshooting with Mario, we developed a solution: the stone surface must be perfectly smooth and clean. I flattened the stone using 240, 320, 400, 800, and 1500 grit wet/dry sandpaper—a few minutes of work needed only once. Make sure to practice contamination hygiene and clean the surface well before proceeding. Then I burnished the surface with 3M lapping film rated at 3 microns. I'll reuse this piece to refresh the surface when the stone loads up. After the final step, I always rub the stone with a melamine sponge / magic eraser to get rid of all the particles embedded in the surface. You can also rub it with a cloth. This burnishing process is time-consuming, but worthwhile if you're pursuing perfection. The results speak for themselves—this mirror edge was achieved using the 800, 2k, 5k sequence in just minutes. Of course, you can't expect microscopic perfection from a 5k stone, but without magnification this is pretty much flawless. And of course, the edge is refined and very smooth, yet ever so slightly toothy.
Store owner replied: Thank you, Benjamin! We really appreciate your detailed feedback and tips — glad the stones deliver the performance you were looking for.
A quick update on the CBN 800 & 2.000 combination. Here is another shot of a knife with an M390 blade sharpened with this combination. The mirror, to the naked eye, is exceptional. Of course there is a shallow but consistent scratch pattern visible upon close inspection, but you’d be fooled that this is a true mirror to the naked eye. The 2.000 CBN will leave a toothy but highly refined cutting edge. The knife / edge shown has not been stropped and will shave hairs easily.
Store owner replied: Hello Benjamin, Thank you for sharing your detailed feedback on the CBN 800 & 2000 combination. It’s great to hear that the finish delivers such an impressive mirror effect to the naked eye while maintaining a toothy and refined cutting edge. M390 is a challenging steel, so your results speak highly of the stones’ performance.
As promised, I also added the 2.000 to my arsenal. Again, I have been sharpening knives for more than 20 years and have extensive experience with all kinds of sharpening stones, including the resin bonded diamond stones from Matrix. The Hapstone Premium CBN stones feel more like hard and smooth resin stones than typical metallic stones like Atoma or DMT. You get the nice feedback but without the dishing and with the added benefit of being and staying absolutely flat. As stated in my previous review, the CBN 800 leaves an excellent finish. It cuts fast and extremely clean. The bevel has no business looking this satin and I love it. The cut is toothy, yet refined. Easily a good place to stop and enjoy your EDC knife. The 2k cuts at what I'd call normal speed, but at that stage - jumping from the CBN 800- only a few strokes are required to polish the bevel to a very refined level. Im-pressive! Please see the level of polish for yourself. No strops were used, no other tools or abrasives other than the Premium CBN 800 & 2.000. My method: 1.- When using the stones for the first time, remove the silver coating to reveal the brown / copper colored stone beneath. 2.- I personally only use one direction for my strokes to keep everything consistent: I use edge trailing strokes, that means I pull the stone towards me. I avoid "rubbing" the stone back and forth as it is detrimental to a clean bevel at times. 3.- Use even and consistent pressure. Not no pressure, but also don't press down. The weight of the stones usually is enough.
Store owner replied: Thank you for this detailed and thoughtful review! It’s an honor to receive such high praise from someone with your sharpening experience. We’re especially glad to hear how well the Premium CBN stones are performing and that the 800 and 2K combination delivered both speed and refinement without the need for stropping. Your method is spot-on — consistent strokes and pressure make all the difference, and your tip on removing the silver coating is very helpful for new users. Thanks again for sharing your insights — and those results speak for themselves!
These stones are something else. I have been sharpening and using all kinds of sharpening stones for over 20 years now. I really like hapstone as a brand and these stones do not disappoint. I strongly recommend, however, to give these stones an initial conditioning. Nothing special, just rub it with another coarse stone or use a Nagura of sorts to remove the silver coating on the surface. Takes a few seconds and reveals the full concentration of abrasive. It makes the finish less fine (of course) but more consistent and also more in line with the designated grit rating. My 800 cut like a slow 1.500 when it came, after ten seconds of “opening the surface” it cuts like a very fast 800 but leaves shallow scratches, just as advertised. I am so pleased, I just bought another 2.000 and will use that as a foundation to jump to 6um and then 3um lapping film for true mirror edges.
Store owner replied: Thank you for the detailed and insightful feedback! We’re glad the stones exceeded your expectations — and appreciate your tip on surface conditioning. Enjoy those mirror edges! — Hapstone Team

Me encanta como come acero
Store owner replied: Thanks for taking the time to leave a review, glad you like your new stones!
The 50 grit goes through super steels like a beast. It should be noted that the difference between 50 grit and 80 grit is very wide. I use it to quickly re-profile my bevel and go very lightly when I get close to the apex. The 80 grit is a bit slow for re-profiling on super steels, in my opinion.
Store owner replied: Thank you for sharing your experience with our 50 and 80 grit diamond stones! We're glad to hear the 50 grit is working well for re-profiling super steels. You're absolutely right, there is a significant difference between the two grits, and the 50 grit is definitely the more aggressive option. We appreciate your tip about using a light touch as you approach the apex – that's great advice! We hope you continue to enjoy using our diamond stones for your sharpening needs.
Hapstone stones change the way of sharpening with greater efficiency and durability. The 80 grit stone quickly eats the excellent steel for profiling razors and super steel knives as well as softer kitchen steels without fear of wear of the premium Hapstone stones with these stones, rest assured that you are with the best of the best, thanks Hapstone
Store owner replied: Glad everything went well, I wish you high results !
Thank you Hapstone for the quality of these Hapstone premium CBN stones, they are another level, ready to be used and leave an extraordinary edge. They are 3 millimeters thick, which makes them very durable before you buy others. It will take many years. I truly recommend this CBN sharpening stone. premium thanks

Store owner replied: Thank you for your review, Dmitrij! We're glad you're happy with the Hapstone Premium CBN stones.
If you want some of the best stones the market has to offer, this is the right choice. The low grits works fast and efficiently. The blanks the stones are attached to are really good quality, easy to read. The higher grits works fast stones gives a beautiful polish, and yet has amazing bite. I use my stones with the oil hapstones makes, makes cleaning the stones a charm.
Store owner replied: Thank you for sharing your experience, Steffen! We’re thrilled to hear the stones are delivering both performance and finish you were looking for.
Brilliant. Cuts really well. Found that using honing oil keeps it clean while sharpening. Lovely stone
Store owner replied: Thanks for your feedback, Mark! Glad you’re enjoying the stone.

Много добре
Store owner replied: Благодаря, Viktor! Радваме се, че сте доволни
Nice stone. Has a very good bite, but without leaving to deep scratches. It moves a lot of steel so perfect for reprofiling any blade i believe..
Store owner replied: Thanks, Peter! Glad you like the stone - great to hear it cuts efficiently while keeping the scratch pattern controlled!
Камень стоит своих денег.
Store owner replied: Спасибо за отзыв! Рады, что камень оправдал ожидания — пусть служит долго и эффективно!
Muy buena calidad
Store owner replied: ¡Gracias por tu comentario! Nos alegra saber que estás satisfecho con la calidad 🙌
Perfect, super stone that I use with the rest of the CBN premium range.
Store owner replied: Thanks for taking the time to leave a review! Great use !
With these stones, you could stop at 1500 or 3000 grit and already have an excellent cutting edge, but with 5000 it's even better!
Store owner replied: Thank you for your experience with our stones, we wish you excellent sharp blades !
Really good, like the whole premium CBN range
Store owner replied: Thank you for your review, we are glad that you like our hybrid stones !
The finishing touch for an ultra-clean, mirror-finish cut.
Store owner replied: Thanks for the great review, stay tuned !
Recently upgraded my sharpening system to the Hapstone RS and a set of the Hapstone premium CBN stones. I absolutely love this setup can't say enough good things about it. Build quality seems top notch and the CBN stones are fantastic. Hapstone recommended using their magic oil with the CBN stones and that was a really great recommendation. I also purchased the case for the system and that is also very convenient and high quality if you sharpen infrequently and want to be able to safely store everything.
Store owner replied: Thank you so much for your positive review! We're thrilled to hear that you're loving the Hapstone RS and Premium CBN stones, and that our Magic Oil is working well for you. It's great to know that the case is proving to be a valuable addition to your setup. We appreciate you sharing your experience and are glad we could help you elevate your sharpening game!
