In the video I may have incorrect stated these were polycrystalline diamond stones. On the listing, I missed that the Company states they are coated with monocrystalline diamonds. For now we’ll just assume what the company states is true. And ill report back if anything changes.

[@EDCandLace]

All diamond stones, be it plates, resin bonded, Metallic bonded, super vitrified diamond all use Mono crystal diamonds. I've never seen ANY stone use poly diamond

I’m pretty good at sharpening knives, but I only dream 💭 of being able to sharpen like this guy does 😅…. Truly impressive, and I’m often jealous watching these videos …. Still I am and always will be subscribed, you thought me the proper way to strop, since then my edges have been 50% better when I’m finishing on 3 micron .. very fine leather strops

Thanks for including the timing - when we watch youtubers sharpen at speed it's hard to tell how much time we should expect to spend on each knife. Thanks also for the advice on not using water on the diamond plate - lots of conflicting info on the Amazon listing.

After watching this I picked up one of these S SATC stones/plates and I'm pretty impressed. I basically sharpen on the 400 side and deburr on the 1k which works pretty well. It's surprisingly good for twenty bucks, so much so that I just ordered another to leave in my work knife roll. Thanks!

i got the exact same stone and it has been serving me fantasticaly for learning and getting pretty good at sharpening, but i am now thinking of upgrading to finer grit stones aswell

[@rAustinBall]

love your videos. got this stone and a Shapton 2000 because of your work. One thing I haven't seen you address is using some sort of lapping fluid on the diamond stones. I think it would be a good subject for a future video.

[@mladenvojinovic]

Great video as always. Thank you mam

[@birddog61999]

I have had that same stone for about 3 years, it seems to have held up well for me. I would say the 1000 on mine is not quite 1000 but it is much closer to it than the 400 on mine.

[@hersch_tool]

I use the single sided finer grit versions of these to hone carbide lathe tools, they work well enough for that.

[@hellhound2260]

I just realized when I saw this video recommended again that it's literally 4 minutes and my brain went blank for a while because I remember when I was watching the amount of information that I've gotten from it made me think it was about 10-15 mins, very laconic.

[@webderek]

Excellent review and micrographs. Thank you. Have you ever used the 1x6” stones designed for the EdgePro-style sharpeners? A whole set is about $25 and double sided tape works well to stick them to a board so they stay put. I just use them with an edge marker and hold the board and stone in my hand and set the blade on a chunk of 2x4” as a base to get the tip off the counter. It’s a lot faster to learn this method because you can see the marker being removed, since the edge faces up. So you can adjust the stone angle more quickly.

[@thalegacy6]

I use this set a few times a week sharpening our circular blades at work. I use the 400 then 800.

[@JACJAC70]

Thanks for the review. This looks to be an adequate single-stone solution for a beginner looking to keep their kitchen knives usable, unless you have any other suggestions.

[@bryceborcovsky8979]

I bought something similar to this stone for removing metal quickly from knives and then finished them with my Spyderco stone and was happy with the results however the diamond stone has worn down quite a lot and it now takes a lot longer to profile blades but still worth the price if you have to remove chips from your knife. If however you just need to sharpen your knives spend the money and get a ceramic stone and don't waste money on crap.

[@wam7484]

I just ordered one of these. I noted that the Amazon ad from S SATC stated to never use it dry and specifically said you could use water but dry it after. This video says to use it dry and never use water. Somebody's wrong. I see several commenters asking similar questions but you haven't answered anyone.

[@jwdory]

I would follow the manufacturer recommendations.

[@clashwithkeen]

I just ordered one of these yesterday. I'm glad I watched this video as per manufacturer's instructions it says do not use dry.

@@OUTDOORS55 I’m very curious what happens to diamond stones when using water because I like to use them with a very light mist of distilled water.

[@OUTDOORS55]

Ill be dabbling in those soon. For the cost i think they are still outside 99% of most people's budget 😕

[@OTOss8]

Cool video man. I was using some stones that are very similar from Amazon to sharpen up some knives yesterday. They look virtually identical except it's a pack of 5 stones. 400/600/800/1000/1200 I didn't expect much from them but they're much better than expected for the price (about $20). I'll apply your advice with these stones to my diamond stones. Cheers.

[@MinZilla]

Hey, I think I found those exact ones too How are they holding up, can you recommend them?

[@RondeLeeuw]

​​@@MinZillaI think the five-pack comes from the same manufacturer, except they're very thin, instead of having a thick, solid aluminium base. This can be solved by fixing them to something like a piece of wood. I use magnets embedded into the woods to keep the plate into place, which works great! I've used the 400/600/1000/1200 a few dozen times so far, and they're still looking and feeling good. The results are strop-ready.

[@paullmight42]

I've got an edge pro 1k grit on the way...I also got a Smith's hand sharpener bc it was on sale at Lowe's(I also have a strop but no compounds)...Trying my hand at sharpening a few things...the Smith's made something cut paper pretty nicely but no hair shaving...I'm not sure I'm getting a good enough apex to start with tbh...I have a cheapy in 440c that i will practice on once the 1k gets here...Hopefully the Smith's coarse, fine(750) and the 1k will get me to hair shaving...I don't need it but i wanna do it haha...

[@dizzybee7386]

Under recommendation from a certain Nubby stumper, I went for a monocrystalline substrate set up. It was basically down to a choice between Trend or DMT. Trend had a nice package deal on Amazonia of a two-sided 300/1000grit 72" x 2.5" stone with a 300/600grit 3.25"x2" card, lapping fluid and holder for £100 ($121). That was about 5years ago, and I'm still using it and the lapping fluid with ease (there's about half a bottle of lapping fluid left and for reference I sharpen several chisels, plane blades and kitchen knives once/three months average). The 600 side of the smaller sharpening card has gone very smooth, almost 1000 grit, but the larger stone which receives more use has stayed in great state. It's a saving really compared to disposable polys. Stumpy got this right.

[@OUTDOORS55]

Mono does last longer but will be more expensive. Poly cuts faster and deeper and is more sensitive to pressure. If you're somewhat careful it will last a long time as long as the plating is done correctly.🙂

Hi, as someone who doesn't know anything about sharpening, love the videos @outdoors55. I'm considering buying this stone as I can't afford anything expensive. For someone who can only afford one to sharpen kitchen knifes, is this (400/1000) combination the best option or the other 600/1200 they sell? Thanks

I use a diamond chinese stone that exact one from Amazon.. With trend lapping solution. How do you clean the particles off the stone (not using water) off the steel base metal?

[@wasylbakowsky5199]

Chef knife from my wie's dad, someone had tried to sharpen it with a grinder, was pretty brutal and I have made several attempts to get a proper bevel on it with the Shapton glass stone 220, a lot of work. With not much further work, bevel is near perfect this cheapie, needs only a touch more with it. Paper-cutting sharp. This is what I was looking for, a faster bevel setter than my Shapton. Here’s the thing though, the scratch pattern of both grits on a knife blade is the same, so what I’ve ultimately purchased is a double-sided 400 grit diamond stone, for me in hindsight, it’s a bonus! I also have the Shapton glass at 1K, which is perfect, I didn't need diamond plate for that grit, so no loss

[@bigwoody4704]

I want to hear some stuff about the Spyderco CBN plate as far as how its holding up and stuff

[@twatmunro]

I've got one of these. I use it to flatten my good whetstones.

[@williamw7134]

Another thing I've seen on amazon are full size (mostly) diamond sharpening plates at an astounding 6$ a pop. For some reason the coarser stones (400-800) are more expensive than the finer stones (2k-3k) which I thought was pretty odd.

[@OUTDOORS55]

China seems to be able to produce these very cheaply. The biggest problem with them is the grit contamination. It exists in every "cheap Chinese made" stone I've tried. Id be waryof the SUPER cheap ones as ive had the diamonds scrape off of them first sharpening. And they are more like 50 grit super coarse. With more expensive stones you get less contamination. For some this isnt a problem since they have finer stones to finish on. Also you can't make a diamond plated stone finer than about 1200 grit. Since the abrasive is so small at that point the plating is difficult to adhere without covering the abrasive. So anything advertised over 1200 is just not true. Hope this helps. 🙂

[@ianbaker4295]

At this price point. I cannot believe that it’s basically flat. I have two single sided Diamond flattening that have a little grit spattered around the back and edges. None of my double sided plates had contamination but I definitely paid for quality control. 20 dollars is nuts for a usable diamond plate

[@OUTDOORS55]

I may have gotten lucky with mine. I cant say anything for quality control. Mine was super flat surprisingly. Ill probably use mine to flatten my other water stones 🙂

[@karelenhenkie666]

I have one of these and although its not great i use it daily tk keep my waterston3s flat and about once a week to reprofile a plane blade or chisel.

[@oTEMPE5To]

I keep some aliexpress diamond plates on hand purely for reprofiling. I can't think of a better bang for my buck at $1-2 each. I use them before going to my Shapton glass stones. They definitely have some anomalies in the plates but once I get to the 500 Shapton, everything gets smoothed out nicely. :)

[@OUTDOORS55]

You can do that too. I wouldn't use a stone you're fond of to do it though. The diamonds can in-bed themselves into the stone surface and are hard to remove. 👍

[@mystixa]

I did not know that. ..thats super handy info. @@OUTDOORS55TIL

[@peanutbutterbean1738]

a local shop has an almost identical stone, only difference is they are one sided and under the name 'toolshark' and come in a 400, 600 or 1000 grit option and the 400 grit is R200 (~11USD). looks like they come out of the same factory as the S SATC stone, will probably give it a go some time and see how it compares!

[@peetsnort]

I got one 5 years ago for 4 pounds. sterling.just the 400 grit. I glued it to a plank. Good little thing. I always just wet it and it's quick for putting on an edge. I think it's been excellent for the money. I bought 2 and have yet to break the new one in

[@sharpwhits0167]

Get a cheap arkansas pocket stone and scrub the plate before use with ark pocket stone, keeping everything wet and rinsing the fractured diamond residue washed off. Once the plate has a consistent smoothness, it's broken in.

[@jasoncampbell6222]

I bought from Amazon the Sharpal Diamond Stone Dual 325/1200, initial thoughts were that it was garbage and after deciding that I'd give it sufficient time to break-in concluded that it was still garbage despite it being mono-crystalline diamond. Returned to Amazon just before return period expired and went back to using my trusty 1x30 for all my sharpening needs. Would consider getting the ceramic stones but for the cost and time required to get the hair popping edgeI'll stick with belt over stones.

​​@@lawrencem5943I have read several reviews on Amazon saying that the stone chips very quickly with just a few uses(with photos included), and I say "several" because there are actually many. That's why I'm asking if you could share your experience with it 🙏(I've never used a diamond stone before).

[@lawrencem5943]

@@justananarchist680 The Sharpal like the SATC (I have one) will have loose diamonds that will be coming off easily for maybe 15 sharpenings, then it will break in. The Sharpal in my opinion is a slightly better product than the SATC. When I initially started using both of them, I couldn't tell the difference in grits between both sides of the stone, probably because of cross contamination, but after the break-in period I can tell a difference. I think both the SATC and Sharpal's grit rating is too high, they seem to have an actual lower grit level than what they are advertised for, perhaps 200-300 grit too high. I recommend that you use cheap knives to sharpen when starting out until you know they are broken in, then move onto your more favorite steels. At the moment all I use is the SATC and a medium Spyderco (1200 grit-ish) and they work well together. I also strop my knives with 3um and 1 um Gunny Juice and I am able to split a hair by running the hair over the blade. I am getting the itch to move onto a higher rated diamond stone, but for now I am satisfied with the SATC like I was with the Sharpal.

[@kxrsuperstar]

I’ve had this one for 8 months. The 1000 side is still courser than the DMT 325 single side. It’s a beast. Unfortunately, I’m still stuck on profiling stones. Can’t seem to get a sharp edge on anything over 1000. Even the Shapton gives me trouble.

[@twatmunro]

Stones over 1000 are really polishing stones, not sharpening stones. I use a Shapton Kuromaku 320 for my initial sharpening -- to establish the apex and the burr. And then Shapton Glass 1000 and 6000 to refine/polish the edge. In the past, I used to sharpen on a King 1000 but it took forever when compared with the Shapton 320

[@W_H_K]

Atoma FTW! EDIT: DMT leave a nicer scratch pattern but Atoma are better quality in my experience. Atoma have an interrupted pattern whereas DMT (some) do not. I buy 2 Atoma with bases and 2 replacement grits to stick on the other side. Four grits in two plates. Originally I bought Atomas as Waterstone flatteners but tried them as sharpeners and really liked them. I have that stupid expensive Shapton Glass Diamond flattening plate as well. 😂 lol there was another even more stupid expensive, the Shapton Kubo….I never did buy that.

[@anzov1n]

Any alternatives since this one is no longer available? Plenty of similar products on amazon but really hard to tell if they're at least on the same level of quality. I'm guessing it is best to avoid the thin ones due to flexing/flatness concerns?

[@flogut1]

Hi outdoors55, not related to 😊this post but need your opinion. Referring to fixed knife jigs. Does the angle vary from 90 deg below the pivot to the extreme edge of a long blade. I think that the bevel is smaller and steeper at 90 deg than at the extreme edge of blade because of the lower angle causing a wider bevel. Mainly on longer knives. Some say same angle regardless of blade length. Thankyou should you are able to comment. Mal.

[@vonSmash]

I'm looking for the diamond stone you're showing in this video, but the link in the description goes to a Kalolary Whetstone Knife Sharpening Stone 1000/4000 Grits instead. I'm no sharpening pro so I can be wrong but from watching your videos I think I understand that these are two very different stones used for different reasons, right? Your link goes to the same whetstone in other videos too so I'm confused as to why and where I can find the Diamond stone you're showing in the videos?

[@justplanefred]

I ordered from your link and it was unavailable and recommended a set of 4. 400, 600, 1000, and 1200 on thinner plates that are foam backed. They aren’t bad but I need to learn how to get a consistent angle so I don’t need to keep using my Lanski sharpening system…

[@mauricioruiz9021]

Would you recommend this stone for a mora? I usually use sandpaper on a flat surface but sometimes I'd like something that would last a little longer for rough sharpening. Most of the polishing I would still do with sandpaper

[@OUTDOORS55]

You do need a very coarse stone for scandi grinds, since they are a pain in the butt to sharpen. If you have a way to refine the edge after initial profiling then it could make a somewhat decent candidate. If you sharpen A LOT id recommend something like the DMT extra coarse. Its much more expensive but will last longer. This stone is fine for the occasional use for only $20

[@undeviljur]

First of all I love your videos and learnt a lot from you over the years. Thx for that. But I'm not sure about the part ware you advise never to use water on nickel-plated diamond stones. my experience is that DMT diamond stones clog up without using water. It is definitely a problem when sharpening chisels with a honig guide. Did you have problems in the past with them corroding? I would love it if you can make a video about this and share your reasons for that advice. I have actually ruiend one of my DMT fine stones by not using water and pushing harder when it was clogged. This made a portion of the stone so dull it does nog cut anymore. my new stone is still cutting super well sinds i use water. But i clean and dry off the stone really good as soon as I'm done using it.

[@OUTDOORS55]

After having manufactured my own diamond stones and experimenting with different methods, base steels and abrasives I've come to the conclusion that water is the number one killer of plated stones. I recommend Just useing a towel to wipe them off. They will corrode eventually with water. Depends on how much you use them. You can't really ruin them by pushing too hard unless there was a problem to begin with, which is a possibility. Or they are polycrystalline diamonds (which dmt doesn't use). If it works for you than go with it👍

[@tyrotrainer765]

I ruined my first diamond stone by using water, it corroded in no time. I then saw a YT comment recommending using isopropyl alcohol. It is brilliant, it lubricates well and wipes off dry.

[@handleshtick]

I was wondering this same thing! I just bought/used a diamond stone to restore/sharpen a hand plane iron and used water to clean off all the steel I was removing. After doing a bit of googling I don't see the same advice repeated anywhere; in fact, a number of sources say you definitely *should* use water. Huh.

[@undeviljur]

@handleshtick I think it's very important to dry the stone well after using water. And when sharpening a knife, it's not necessary to use water. But with plane blades, you tend to use a lot more pressure. The water prevents the steel particals from clogging the stone in my experience.

I have it too, plus the three Shaptons Outdoors55 has. The stones are indeed faster and easier to set up. If I have to maintain or re-profile a v-edge, the KME is perfect. If I want to sharpen my kitchen knives or any other blade which already has an edge that's more or less convex, I go for the whetstones.

And also for the scandi blades: forget guided systems. Scandis need the stones.

So why no soapy water on diamond plates? Just because of the rust potential from not drying thoroughly after use, or another reason? Can it degrade the abrasives bond to the plate? I’ve never sharpened dry before, I tried it when I got into diamonds, but it just felt “wrong” to my water/oil stone conditioned brain. But that means I have no comparison of long term effects of using them dry versus wet.

[@OUTDOORS55]

After having manufactured my own diamond stones and experimenting with different methods, base steels and abrasives I've come to the conclusion that water is the number one killer of plated stones. I recommend Just useing a towel to wipe them off. They will corrode eventually with water. Depends on how much you use them. You can't really ruin them by pushing too hard unless there was a problem to begin with, which is a possibility. Or they are polycrystalline diamonds (which dmt doesn't use). You can ise water but you will get more rust over time eventually killing the stone. Especially if you use it daily since it never has time to completely dry. Just my findings your mileage may differ 👍 Edit sorry this was a reply to someone else but i think it actually answered your question too😂 Thanks for the comment 👍

How are they holding up after 2 months of use?

[@Lumpy_Peter]

Given the contamination problem, would it be wiser to buy this in a single sided version or would the contamination be the same? Also, for somebody building his sharpening system from scratch, would you recommend a combination of this 400/1000 cheapo diamond plate & 1000 shapton stone or would it be better to get 200/600 diamond plate for reprofiling & shapton 1000 grit?

[@OUTDOORS55]

It may be better but it depends on how they clean the tanks when they manufacture them. Cant say for sure..

[@OUTDOORS55]

Id get the 400/1000 and the shapton 1000. Unless your blades are in Really bad shape. The 400/1000 is really coarse.

[@Mrplacedcookie]

Never use water? Any reason for that? Care to elaborate? I use water sometimes and are careful of of padding them dry to evade any oxidation. Thanks

[@norbertnagy5514]

You answered your own question

[@razorbackss]

I use these little suckers for my sharpening classes, perfect for beginners. You had a crack at the atoma 140 yet?

[@OUTDOORS55]

Not yet🙂

[@razorbackss]

@@OUTDOORS55 you of all people will appreciate it. 👍

[@bentravis99]

The "S SATC Diamond Stone" is unavailable now, are there any other stones you would recommend in a similar price range?

[@domi2023x]

I watched some other videos where using water on diamond stones was recommended. Why do you think it's best to never use water on diamond plates?

[@JohnSmith-gs4lw]

I have that same stone and so does a friend at work. In both cases, we’ve found that there is not as much grit on the sides/edges as in the middle. Hard to sharpen a knife blade when you can’t sharpen the back centimeter of the blade. Would be fine for chisels.

[@lastelinl8724]

It is good enough. After getting a decent edge I can finish my knives on a Japanese Waterstone, but I do it only if I have the time. Unless you are a knife junkie who can't sleep because the edge of his knife doesn't look perfect under microscope, you should be fine with this.

[@XA--pb9ni]

i don´t thing the brand matters here. It is just a marked up diamond stone. S Satc also sells these cheap AF aluminium oxide sharpening stones.

[@damirelsik4996]

I just want to sharpend carbon steel Mora knife when in woods, loot looking for magic, what would work for me? Something compact.

[@thechumpsbeendumped.7797]

Why not use water? I use a fixed geometry sharpening system and have always used water to sharpen and had no problems with corrosion.

[@OUTDOORS55]

You will get corrosion at some point. Especially if its use regularly.

[@fujimeira]

Damn, that very same stone cost 135 AUD (~90USD) here in Australia as of 6th Jan 2024

[@dylandevoto8315]

Hey man I am confused about what you said in reference to using water on a diamond stone. I have a DMT diamond stone and they recommend using water, as do other sources all over the internet. I also didn't realize until now that you've stated that they wear out rather quickly.... is that because you use them dry? Possibly? I'm just trying to get the most out of a $50 stone that I still don't feel confident when using it. Lol I'd love for you to make a video about DMT stones specifically. I use either water or a solution of water, dish soap, and windshield washer fluid, like what you put in the reservoir on your vehicle. I made the investment because I wanted something that I knew would be flat and sturdy but it feels strange when I use it. I probably use too much pressure.... I'm going to get one of those ceramic Sharpton stones next but it'll be a while before I spend more money on knife sharpening stuffs. Thank you for always making videos with a good attitude and good intentions to help people like me who didn't have anyone to teach them how to maintain the world's most handy tool!

[@OUTDOORS55]

You can ise water but in doing so the stone will rust. Diamond stones don't need water or fluid to work properly. You can simply wipe off the particulate with a towel. Mine are 6 years old and used HEAVILY and I've never used water on them.

[@dylandevoto8315]

Right on man I appreciate your reply. After I posted that I comment, I tried my diamond plate dry and it felt good. That when I realized that the only time I'd tried it dry was before I'd properly broken it in. Thanks again

[@CheeseFriesAndCoffee]

Is it a bad idea to use water on ANY diamond stone or just not on these? I'm asking about the ones that come with the worksharp precision adjust.

[@no.no.4680]

Pretty much any. Even if the manufacturers claim it’s safe for water, whether it’s corrosion resistant plating or stainless, rust will still find a way. Stainless isn’t completely rust proof, and plating will be worn away with use. Even some of my stainless steel spoons have rusted after decades of use. Gotta scrub it off every time I see it or toss em. 😂

[@imranbashiruk]

Could you explain why you don't use water with diamond coated stones and what happens if you did use water?

[@norbertnagy5514]

The steel that they are glued to can start to rust

[@norbertnagy5514]

Maybe you can try with water, if you can dry it fast and adequately after

[@jobsearch5871]

use mineral oil. Same mineral oil but at a cheaper price is baby oil.

[@roylerroycerickson]

What about compared to a DMT?

[@ghidfg]

why is it not advised to use water on diamond plates? is it because of corrosion? would it be okay if you dry it after use?

[@OUTDOORS55]

Use dry. They will rust under the plating

[@american1911]

Please explain why water is not recommended for poly diamond.

[@norbertnagy5514]

Not because of the diamond, its because the steel plate that they are on

[@kevindeuschle3413]

Hold up, why would water cause premature wear on a diamond plate. If anything it helps float away swarf, and broken off loose diamond particles reducing wear on the nickel plating holding the diamonds to the substrate.

[@norbertnagy5514]

Corrosion on the steel

[@norbertnagy5514]

Some encountered it in the amazon rewiews too

[@muhammedk470]

Hi. If you shouldn't use water what can you use. Paraffin?

[@OUTDOORS55]

No...nothing is needed on these.🙂

[@leotam3372]

Wait, why not use water? I thought water helped float the steel dust off the diamonds

[@megapro1725]

why you're saying never use water, when dmt, venev recommends using it?
