Why I'd Avoid This Spyderco Sharpening Stone - CBN VS DIAMOND -Spyderco CBN Benchstone Review

[@scottbennington2936]

I remember when you would pull your lawn mower out, do the knife build. Get interrupted by the trash man. The lawn guy. The wind blowing. Finish build. Hack up a 2x4 with new build and /or run in the woods for a mini movie on jokers. Glad you have made it to the big leagues. Many here have learned so much from your time and teaching abilities. Godspeed Sir!

[@ryewaldman2214]

The spyderco double stuff 2 with the CBN coarse side and the ceramic fine side is much more high value as far as spyderco sharpening stones are concerned. The CBN (like diamond) let's you sharpen even the s110v blurple and gray maxament knives, while having a usable ceramic hone on the back side. I also really like how they beveled and rounded the edges of the stone so you can access serrations, recurved edges, etc. Very handy little multipurpose sharpening stone when you want something pocket sized to throw in a bag or took kit. As far as dual-sided plates go, I'm 2 for 3 with the DMT diasharp double sided stones. I have a coarse/x-coarse stone and a fine/x-fine stone that don't suffer from awful grit contamination; however, i did get a fine/x-fine stone that DID have terrible grit contamination on the x-fine side. I have had really excellent results from dual-sided venev diamond waterstones. These are better because rather than plating single layer of diamond on a metal substrate, there is about 2mm of a diamond-impregnated matrix. The matrix is then bonded to a center plate. In this case, since the two grit sizes are formed separately, there isn't a problem with cross-contamination. These venev diamond stones really cut rapidly and leave much more refined edges than you'd expected from their grit rating and cutting speed. I think they really are the best sharpening stones I've ever used.

[@fuzzynuttz5092]

I recently got the hapstone premium metallic bonded cbn stones and they're pretty good stuff as well

[@DanialY-qm6xt]

Jsyk, do NOT get the Venev resin-bonded CBN stones. They have absolutely terrible QC.

[@ironhead65]

I think I want to disagree between diamond and CBN just to meet you! Thanks for the video, I love this new format and everything you’re doing. It’s really helping me understand really, what happens instead of all the hocum and crazy behind-the-scenes magic that you typically get from people when they tell you how great something is for sharpening. When they really mean, it’s really great for the exact situation they are using it for in the exact way they are using it, and they lead you Intentionally or not in the wrong direction

[@Heracleetus]

In my experience it's true, but it's an excellent idea for a video 👍

[@otobotrecords]

Well in my case it's Franconia. Where is Bavaria located again? 😅

[@uponeric36]

The real issue with sharpened knives and the dishwasher is that they don't need it, and water isn't safe for all steels and handles. It's a stupid risk when the right solution is the sink a few feet a way and half a minute of hot water - not to mention a waste of time and dishwasher space when no knife is so dirty to need one! Unlike a plate, a chef knife doesn't often get covered in dried spaghetti sauce.

[@FreedomFox1]

When you said “for good” at the end, it was expecting the shed to blow up or something.

I think the best "dual side dual grit" plates. Are if you buy an Atoma plate, and an Atoma replacement sheet in a different grit and put the replacement sheet on the back of the clean Aluminium plate.

[@brianlawson3757]

Last year I bought a Spyderco fine, double-sided stone that I think they discontinued. I think you reviewed it some time back and I happened to snag one before they were dropped from Amazon and it's worked for me so much so that I don't bother with my composite stones anymore. They're too messy and always need flattening, which is a pain.

[@robohippy]

CBN was developed specifically for sharpening high speed steel, which is what all of my wood lathe tools are made from. Diamond does not work on grinders because the heat destroys them. I do have a couple of CBN slip stones in my shop, even one that is double sided. They are far higher quality than the one you show. Mine came from D Way tools up in Washington. They can be made to any quality, the manufacturers just have to know what your demands are...... I do have diamond for all of my flat work tools.... chisels and bench planes.

[@OUTDOORS55]

It was developed for high speed/ high heat applications. Which isnt an issue with hand sharpening.

Are diamond and CBN stropping compounds also comparable to each other? Thanks for the videos.

[@OUTDOORS55]

[@DanialY-qm6xt]

I've had slightly better finishing/polishing with CBN compounds but just barely.

[@joeyliao8937]

A couple of years ago I bought the Spyderco Golden Stone sharpener (the one that looks like a duck foot). I had bad results sharpening my knives as the blade kept on getting caught on one part of the stone. I ended up buying a cheap diamond plate to grind down the Spyderco stone which revealed a very wavy surface with a couple of nubs right in the middle of the sharpening flat (on both sides). The seams on the edges also stood proud of the flats until I ground them down. I think Spyderco needs to source from better vendors or do some QC to make sure the other products sold under their brand are as good as the knives they sell.

[@1947froggy]

So what causes a stone to be grit or not grit contaminated? What makes it susceptible to contamination? How does it resist contamination? Any way to clean it?

[@sharpwhits0167]

I found mine to cut very efficiently. But, for a couple of months I could not figure out why I couldn't get consistent edges. One day, I set it on my workbench when I got frustrated with it instead of putting it back in its leather sleeve. BINGO! The damn thing was warped. Not sure why it took so long to figure out. I might attempt to flatten it at some point, but until then it's just a paper weight.

[@jonfeuerborn5859]

You can't see me. 100% agree Alex. CBN has a very specific use case--high speed, high heat applications where the metal and abrasives get so hot that the diamond becomes unstable, and due to the affinity of hot iron for carbon, leaching occurs wherein carbon released from the diamond is infused into the steel, making the surface brittle (not to mention the rapid wear of the diamond tooling). CBN remains stable to higher temperatures and doesn't have carbon in it to foul the iron. If you're doing anything remotely close to that during sharpening, you've wrecked the temper long before you would experience thermal breakdown of the diamond surface. But you know, some people are going to hear that CBN is superior for machining steel, and just run with that idea. I'm actually a bit surprised that Spyderco even offers that thing. They're some of the most knowledgeable steel geeks on the planet. Must've seen some dollar signs flash before their eyes.

[@OUTDOORS55]

Exactly 👍👍

[@bumblebee2989]

What do you think of the Spyderco ceramic stones? I have a medium grit and feel that it works as a quick hone to minimize the burr after a coarse diamond stone. I'd love to see your thoughts on the different grit spyderco ceramic stones.

[@Dynotop1a]

I think this is a good bit of criticism. It would be cool if Spyderco kept improving their abrasives like this plate. I have one and will say that it wasn’t perfect, but it does work for my really toothy edges. I notice a little bit of a difference between the two sides in use, but I would prefer their finer CBN grit to be a tad more fine. Their other CBN offerings are very unique and useful, though. Stand out more from the competition.

[@paulkresky1465]

Thanks for saving us money. Was on the fence about this one, as I really love their ceramic stones. But now I am even more confused. About 10 years or more ago, there were so-called cbn sharpening stones sold at gun and knife shows. They looked like dark black colored aluminum oxide stones, but they stunk to high heaven, and they were very oily. I had a couple labeled under the gun name Winchester. Boy, did they aggressively sharpen fast. They smelled like a tire yard fire. And they were very heavy for their size. They were not metal plates. The package said made in Japan on it. I got talked into swapping them with another maker, collector, restorer. I have never seen another one. I know Smoky Mountain Knofe Works sold them. Wonder if anyone knows anything about those? Mine were about 3 " by 2" by maybe 1/2 inch thick. It never listed a grit rating. Felt smooth, but super aggressive.

[@OUTDOORS55]

Hmm interesting! If you find them let me know!

[@paulkresky1465]

​@OUTDOORS55 I will, Alex. This video sparked my memory of them. Perhaps I can find something on the internet. If I do, I can respond either here, or an email address for you. Paul

[@paulkresky1465]

​@OUTDOORS55 Alex, I found the info! I remembered the gun company wrong. It was Colt. The name of it was Colt C-BNX7, cubic boron nitride sharpening stone. Size was 4" × 2" × 1/2". It was not a bonded metal plate. Amazon still has a picture of one up with the specs. It had about 5 reviews or so, by people saying it was the best stone they ever used. Just needed a bigger one. One review I read was from 2016, if I remember correct. I could not find one for sale on either ebay or amazon. If I did, I was going to try and email you the link. There may still be one out there. I remember my blister packs they came in were bright blue. I agree. They were too small, and really smelly, but one of the best pocket stones I ever owned. I bet the knife forums discuss these. I'm gonna check them myself. Hope you see this Alex. Have a great nite, and thanks for your videos. (I too miss the shed! 😢😂)

[@Heracleetus]

I researched the heck outta systems before settling on the $90 Spyderco sharpmaker with CBN rods. I can't get a good edge on anything and it absolutely destroys the point on every blade you run through it. It also has some defects/bumps on the surface that will blunt your edge. The plastic holder also broke on the very first use of the system now I can't use the scissor sharpening part of it. Oh, and it loads up and clogs so fast I can barely get through one knife before it clogs. Before the sharpmaker I always just freehanded on cheap Norton stones and got way better results.

[@DanialY-qm6xt]

I think your technique might be wrong

[@Heracleetus]

@@DanialY-qm6xt I'm definitely open to that possibility (I also wonder if I might have gotten a knockoff). I watched the sharpmaker video like 4 times before even buying the thing. I tried using the lower angle slots first to reduce the shoulders or give it a secondary bevel or whatever they called it... Didn't really help. The most success I've had with it is freehanding with the rod but that's really unsafe. I've also noticed I get a better edge if, instead of keeping the blade 90 degrees to the ground, I rotate the blade a few degrees away from the rod (thus increasing the angle above 20 degrees)

[@nickwulf]

Thoughts on Spyderco Sharpmakkkkkkkkkker?

[@kevinAuman1]

Yes I agree, my entire reason for searching this stone was to see what grit they claimed the "fine" side was as I've owned it for years and only used it 2-3 times without liking the feedback,feel or results from it as the fine side is like a 325-400grit finish imo even with trying the suoer light handed faster speed method to try n get some kinda polish out of it 🤷‍♂️🤦‍♂️ whatta rip this thing was!

[@RonaldZaZ]

In your last video you told us you can get crazy sharp with a coarse stone and a strop. So why bother with fine stones then? What's the benefit of a refined edge?

[@OUTDOORS55]

It depends on what you are cutting. Coarse edges don't work well for everybody. Shaving for instance isn't very comfortable with a 400 grit edge 🙂

[@Taegashi]

[@_BLANK_BLANK]

The husky dual sided stone seems to be ok, on the fine side. But i think its because its two separate plates attached to a plastic base thing. I just got it at home depot because it was cheap, and figured it was worth a shot. And really its not bad.

[@DconBlueZ]

Thanks for the video, I usually learn something and always enjoy watching!

[@EdgeStoneKnives]

Where I notice a big difference with CBN over diamond is the scratch pattern. At equal grits, the CBN scratch pattern is much more muted and attractive. CBN also seems to cut a bit faster due to its structure and having more facets--the same quality that gives it a nicer scratch pattern. It cuts wide and shallow instead of deep and narrow like diamond. But you're right, zero difference in end sharpness and utility of the edge. Thx for the video!

[@OUTDOORS55]

Thats the thought. In reality I can't tell a difference between pictures at 1 micron between the two. Or any difference when sharpening or in use. 👍

[@thorwaldjohanson2526]

I think the differences are small but there. The structure of the abrasive has an impact. But there is probably just as much difference between different diamond and different cbn stones. The contaminated fine side is a good example, the result depends on several factors such as grain uniformity, grain shape, density etc. But for both materials, the hardness itself is not a significant factor.

[@CraigLuna]

The resin bonded diamond stones have an amazing finish.Definitely not as fast as cbn or plated diamond stones

[@Norman_Fleming]

Love the short and educational videos.

[@richardjones452]

Could be worth another look into the STSC diamond double sided stone. Got one recently and I think they have greatly improved the fine side since you got yours. I find the scratch pattern easily finer than the coarse. They have now put a silly plastic frame around it mind but it didn’t cause any issue

[@TheDuffinator]

Can you demo how to sharpen a recurve or even kukri style blade on a DMT diamond stone? I have difficulty on the inside curves.

[@JackShen]

what do you think of the falkniven DC521 benchstone? That in combination with a strop is my 'lazy' Sharpening process. When I want to get fancy I have the shapton G7 glass stone kit, I picked up the extra 1500 and 5000 G7's since the kit has big jumps between grits. The kit has a stand and a diamond flattening stone. So the process is 600, 1500, 2500, Strop, 5000, and then 30,000. The kit was about the same price as a single glass 30,000 stone.

Wonder whether the DMT duosharp fine/course might be a good alternative as well.

Not that it saves you a bunch of money, still about $100, but it does come with a nice base.

[@imanassole9421]

Question.. so I collect knives.. I have my whole life. (Yes, I barely use them.) Just recently got back into it. Sharpening is something I just haven't got down yet.. and I'm a bit scared to do it with knives in my collection. I bought a cheap whet stone set, then a worksharp guided FS, also a Falkniven d4 for travel. What would be the best way for me to practice hand Sharpening? Should I just use a dirt cheap kitchen knife? Or actually get a decent blade practice on? Something to sharpen, beat up, then sharpen again solely just to practice. As is, I can get a cutting edge on a blade.. but I'd like to be able to get a (comfortable) shaving sharp edge. Like scary sharp.. is my goal.

[@stuartdavenport2952]

Thanks for that video. Along the same exact line, would you mind doing a video on the DMT 1200 mesh stone, the Extra Fine Green? I bought one years ago and it felt like it was a lot coarser than a slightly worn in 600 mesh fine. Grit contamination, I do believe. I sent the stone back to DMT and they replaced it, only to have the same issue. Grit contamination. This is after a break in period. The stones I am referencing are the DiaSharp line, not the DuoSharp. I don't think it matters, but just for clarification. If there is a way you can get your hands on a 1200 mesh 8" DiaSharp DMT stone, I would love your opinion, and the microscope shots, to back it up. Even the DMT Extra Extra fine, their 3 micron stone, feels a lot coarser than 3 micron, and like you mentioned in another video, I don't really care for that stone either. It feels weird. I guess there is difficulty making finer and finer diamond plates. The coarse stones work great. The 600 mesh Fine stone is excellent. I feel problems start with the 1200 EF. However, the Atoma 1200 is amazing.

Unrelated question, but this seems to be the perfect place to ask it. I just sharpened my Gyuto kitchen knife on a shapton 1k, did the forward strokes, 10 each side, alternating, to remove the burr. Stropped on some green compound. It is quite scary sharp, but shaving arm hair works much better when i hold it in my left hand. Hair is just jumping off. When holding it in the right hand and shaving my left arm it kinda works, but not nearly as nice as the other way around. Is this a burr issue?

Is a marble whetstone any good?

[@abrahamkalichman6845]

I would really like to see your explaination or facts on all of the diamond and cbn types of products. Their differences in terms of particular effectivness as well as durability. And why. Oh! I forgot the actual cutting feel of each product. Whether the apex is perfect and burr completdly removed. On all of the various metals that you have so exoertly examined.

[@OUTDOORS55]

There's really not much to go over to be honest. Its not that complicated of a topic. For freehand sharpening there no difference other than the difference grits which should be pretty obvious. Plating quality and grit consistency is the most important. There are different types of diamond as well polycrystalline vs monocrystalline. But it can be very difficult for the average user to tell a difference without already knowing what they are using.

[@abrahamkalichman6845]

Are you telling me that the ultimate durability of the abrasive is not really evident, to most sharpeners. I would have to disagree with your evaluation. In terms of the plating degree of quality would be very important as well as concentration level. This is why all metal played abrasives have a very low level of long term effectiveness. Should never be part of a semi professional or professional work place. ALL ARE VERY POOR FOR Consistent Quality function and well as consistent durability.

[@DanialY-qm6xt]

​@abrahamkalichman6845 knife sharpening is not a machine shop. Plated stones are fine because of the lack of high speed or heat. It'll wear orders of magnitude more slowly than when they're used for machining.

[@abrahamkalichman6845]

Sorry to inform you, but there are more efficient ways to use quality diamonds than a metal plate as a base. First, is that the mono diamond that is used in these plates are very poor in effectiveness vs a poly diamond. The action of the blade across the diamond plate lops off the diamond particles similar to a sheet of sandpaper. Making the plate very poor in its effectiveness. There are other methods that will accept all quality diamonds for a better effective and durable solution. Paste is obvious, as well as emulsions .I'm sure there are slurries as well. This has nothing to do with high speed machining. poly diamond is much more effective but is weak as a body. Mono diamond is stronger but less effective. Especially when it is broken off on every stroke, where the diamonds are adhered to the bed of the plate, without movement. So

What is the purpose of the hexagonal pattern on some diamond stones?

[@tomdowser]

To catch the swarf.... Kinda sucks at the tip

[@jonfeuerborn5859]

Prevents fouling. If you like that feature, you'll have better luck with DMT's stones that have the small holes in the surface. The pattern doesn't tend to catch knife tips as badly.

I've got a norton india oil stone 320-120 grit and i heard india oil stones leave a more durable edge is this true I've also got a king stone 1000-6000 Steel series 240-800 whetstone A few natural stones that leave the most insane edges I've ever done on knives so far

I bought some DMT stones and found the abrasive media was not well distributed. There were lots of blank spots on the stones, I would not buy them again.

It looks like Amazon has low or no stock on almost all the Jende diamond compounds. Jende charges $14 to ship a single bottle or 7 bottles. ☹

Nice close up pictures, thanks.

[@lasserrejeanmarie736]

hello and thank you for your great videos. I am French and I use spyderco ceramic stones (the 3 grits: medium, fine and ultra fine) (for the mirror polish I have a Nahiwa 12000). did you use these stones? I have never used a diamond stone, do you think a diamond stone would be a good addition to roughing up the work? Thank you and see you soon for new videos. Jimmy.

Hey Alex! Love the channel, it got into my youtube algorithm a few weeks ago and I've learnt a lot. Recently I ordered that cheap 400/1000 diamond stone you mention in this video, but Amazon screwed up and I got a set of 400/600/800/1000/1200 plates instead. At first I thought I was in luck, more grit sizes and none of the grit contamination! But obviously these plates are fairly thin and don't have any "weight" to them at all. Do they stay straight? Would love to hear your thoughts on this. Keep up the great content!

SSATC appears to be the same as some of the stones from other brands on Amazon, and the SSATC's delivery date is fairly far out (not through Prime). I would be interested in seeing a comparison between it and one of the identical-appearing brands (the one that shows up most easily right now is a company called Jewboer, which offers a 4 or 5 piece set of diamond stones for ~20 dollars, which appears to have the same hexagonal layout and font on the grit marker). As an update to my last comment about the DMT duo-sharp 2-sided thing I bought... it seems to cut differently going towards the sticker than it does going away from it. Are these things in fact directional? Did I damage my stone somehow (bending the steel mesh on which the abrasive is applied)? In line with your advice from this video, I think I'm just going to stick to the coarse side of thig, assuming I don't just replace it with something more normal.

Thanks for. Sharing. And a trip down memory lane

[@Aexium]

In an era of premium products and "gourmetization" of everything, people will find it hard to believe that a 20 dollar stone can be perfect for initial profiling and doing most of the sharpening job nowadays.

[@CuriousAndy]

I wonder what's your opinion on the so-called Arkansas stones compared to the types you usually recommend.

[@grumpyuncle.]

Good info. Thanks!
