I feel the need to point out that the Shapton diamond plate has a glass back, this is because the glass will stay completely flat. if it were just the metal, it may warp over time. this is important because the glass is what makes the Shapton so reliable. It is part of the utility of its design.
i figured that goes whithout saying, why didnt he understand that. he might as well have asked why they dont just put a metal plate on the glass whetsones.
Metal is not the same as wood, it can't warp. Something like an engine cylinder head can distort if subject to excessively high temperatures and loads. This will never happen with diamond plate.
@@tomtucker83 metal has internal stresses that will cause it to warp up to 5 years after casting. stanley used to season their iron planes before machining them to prevent them warping after theyve been machined flat. please don spit bullshit on the internet if you dont know what youre talking about
Hey just wanted to drop a comment to share that I just used a KING 1000/6000 whetstone to sharpen my first two chef knives today. Both of them were pretty dull to begin with (bought for a few dollars at a thrift store) and I now have two working blades that I can use in the kitchen! Neither of the jobs are anything to go crazy over, but for my first attempt I am happy to have brought two unusable knives to life. Appreciate the videos and the full-length shots of sharpening--it really helped me learn while I was waiting for my whetstone to arrive. I find the whole process therapeutic, I enjoy putting time and effort into things I care about and I feel this activity definitely fits in that category. Much love, hope everyone who is interested tries to sharpen at least one knife!
I was gonna order some flattening stones and you mentioned sandpaper, and I have a lot of them in the garage sitting there for 10+ years lol it’s time to put them to work!!!
So some years ago I started flattening wet stones by attaching a piece of silicon carbide wet&dry sandpaper onto a piece of float glass using spray adhesive. Wait a minute for it to dry, spritz with a little water, and then rub the stone over the sandpaper. Spray additional water as necessary. Works great. Stones appear to be very flat, though I don't have any tool to measure flatness with, so not claiming it's good enough for truly critical applications. But for knife, chisel, and plane blade sharpening it works great. I use 220 grit sandpaper most of the time, which flattens a stone very quickly, but 360 grit works as well, though slower of course. Can't really tell a difference on a 4000 grit stone between the two sandpaper grits, which make sense because you generate a thick slurry of material from the stone quite rapidly.
Thank you! I was looking for a review on a Shapton flattening "stone" and your review was exactly what I wanted to know. I have no problem shelling out the money for it if it'll likely be the last one I buy (or one for for many years) and ease of use is never really a bad thing in my mind. That's exactly what I wanted, thank you.
Hey Ricky, great video as always. I have the Nano Hone Stones. All of those are designed to sit on a stage which you do not seem to have for the flattening plate. This allows you to have them elevated and they do not slip around. The stones are great so far and the manufacturer is extremely nice and helpful. I hope you can review his stones soon as I would love to hear your take on this entire system. Keep up the great work!
I have 220, 1000 and 3000 grit stones. I usually do not use the 220 unless there is something really bad on the knife. But I use the 220 stone as a flattening stone and also cleaning stone for the other two after every use. Works well.
Hi Ricky I have the atoma 140 plate and a Kaiden flattening stone I use the atoma plate for course stones and the flattening stone for higher grit stones and have flattened the flattening stone with the atoma , the atoma brings the flattening stone back to life , did enjoy hearing what other choices are available . Regards Dean From Oz
using the sidewalk is brilliant -- for my badly dished stones it was a great, efficient way to start, and avoided alot of time with sandpaper. I was able to go directly from the sidewalk to 320 grit wet/dry paper. Thanks.
Hi Ryky. Nice video as usual. I have trouble sharpening my kitchen shears and would love to learn to sharpen them. hope you could make a video on how to sharpen kitchen shears. Thanks
Hey man i was just on Instagram and got an ad showing a clip from one of your videos. The knife they were advertising was not a knife you have reviewed so my guess is they're using your videos without your permission. The name of the company was kitchen expert but I can't find any info on them. Thought you might want to know cheers!
Sandpaper on a simple glass cutting board works extremely well. No problems so far. I do find the 80 grit cuts it quickly but use good quality sandpaper and then move to a finer grit for finishing... nice example of various honing methods!
I don't know very much about curing fish, but my neighbor smokes his local fish catches, in his backyard barbecue/smoker, and the results can be canned or frozen. Also, there is marinating and pickling fish, which can also be canned or frozen. I'm up in Portland, (on a bike), so I'll be looking for your results on that search. Stay sharp, Ryky!
I use Wet Sand Paper on top of a plate of glas which is also used for cars. I start off with a 80 and later move up to 180. It takes time but I dont sharpen more then once a week therefore an actual stone would be a waste. Btw there are silicon carbide stones made by naniwa which are way bigger than any sharpening stone to get more even results because there is a way bigger contact patch
I am wondering why the 220 grit wet/dry sandpaper on plate glass isn't the best solution. That would seem superior to me. You can get plate from a glass store fairly inexpensively and then it's very cheap. When everything is dry you can use some spray adhesives to attach the sandpaper down. When the sandpaper needs to change, you use a razor blade to scrape the glass clear, clean it and repeat. I haven't done this myself but tool people swear by this technique as part of the "scary sharp" regimen for things like chisels and planes. Maybe it's in your other video(s) but I'd like some guidance on how to tell when a stone needs to be flattened and how to judge when it's flat enough.
Hi Ricky, can you please review fixed angle sharpeners, like the TSPROF and hapstone systems. It will be very interesting to compare the results of sharpening the same knife freehand and on a sharpener, in time and sharpness test.
Shapton probably uses glass for its stability- aluminum and steel are (at least compared to glass) vastly more prone to warping and deforming. Cast iron can, tecnically, be as stable as glass, but it's like wood- cutting and dressing it can change internal tensions and cause it to warp. Glass is fast, reliable, and cost-effective for production.
Nice video Ricky! Question for your next Q&A: I really struggle to get the tips of my knife sharpened like the rest of the blade because of the curvature (chef knife, petty knife, etc). I end up using a more aggressive sharpening angle to get the job done, which is probably not the best way to do it. Could you do a tutorial on knife tips sharpening? Thanks a lot and keep up the good work!
Would like to hear more about the Atoma. Is it how much (%) slower than the shapton flattening plate, please? And I would have loved if you did put all of the methods in an order: from fastest to slowest and picked up your top two or three favorites.
I use Atoma "400" (it's 320 in reality), and it's very fast to flatten with, couple of strokes and the stone is all flat. For higher grit stones (King 6000) I use the Atoma 1200, the 320 grit version is to coarse. I can use it on it's back or rubbing it against the stone. It has a nice pattern to channel all excessive slur coming off the sharpening stone, so you don't have to worry about it. I can only recommend it. I use the Atoma "400" and the 1200 for repairing and sharpening knives, as well. It's nice big, 8" x 3" (210 x 75mm). You can't go wrong.
got a whetstone today only to realize that they can dish thanks for the tips but where i live (india) i dont have any smooth sidewalks will rough sidewalks work?
I tried to flatten a whetstone with sandpaper but sandpaper got destroyed... will re try in the future with different sandpaper. The plate that you got milled what metal was it ? aluminium?
I never did purchase one of the Norton flattening stones due to too many "not flat" reviews on Amazon. I guess though that compared to a sidewalk it may be the same.
There are really cheap diamond plates on Amazon. Like a set of 6 for 20€. I glued them on some plywood because they´re just about 1mm thin and they´re definitely good enough for flattening stones and sharpening. They´re just too coarse for polishing, but that´s where the chosera 3000 comes into play.
Sanjeev 45% of the world’s population live in rural areas. I’d have to walk almost a kilometre to the nearest sidewalk. I have sandpaper in the shed behind the house.
Is it a feasable idea to buy a cheap 250k stone to flatten a cerax 1000k stone? And getting a cheap 800k stone to flatten a Rika 5000k stone? If anyone knows please help me out. Thanks in advance.
I found that the sandpaper method didn't work so well with extremely dished out stones. I had a very curved King 240 stone and I've dulled at least 5 different sandpaper sheets (high quality ones). What did the trick for me is adding some 60 grit silicone carbide "powder" on top of the sandpaper. This way I was finally able to flatten the stone after about three tries without the powder. Tried the sandpaper method on a 1000 grit King, too. There I had the problem that the sandpaper ground the stone flat or something, the stone was not removing any metal after that. Touching up that stone with the carbide powder helped to reactivate it. I have to note however, that I let the stones to curve way too much, I hadn't flattened them for years in sporadic usage. Do you now how well rubbing different stones together works? How long is the lifespan of an Atoma 140 if it's used to flatten rather course stones, like the Shapton pro 120 or a King 240? Is that even a good idea?
Hey, I just bought a whetstone kit to try and sharpen some old kitchen knifes I have. We have a fairly nice chefs knife that has never been sharpened, and at some point developed a nasty bend at the tip. The knife itself is fairly straight, but starting from maybe an inch from the tip there is like a 20-30 degree bend. I tried just bending it cold in the opposite direction, but it won't budge. Im considering using a blow torch to try and heat it up and then straighten it. Then try and re heat treat it afterwards. (Im not sure if it is heat treated, but i think it is based on how flexible it was without deforming, ill check with a file before i start) Do you have any recommendations or suggestions? Or is it a dumb idea that i should not even bother trying. Thanks for the help. I really enjoy your videos btw. I recently stumbled upon your channel and i find them extremely interesting, informative and well made.
Heat treating is no small matter. The temps involved will destroy any handle material, so you can plan on removing/replacing the handle before you even consider heat treat, then there's the matter of temperature control, particularly if it's a stainless knife. Simple answer, don't, the chances of success without a lot of specialized equipment are pretty low. You could try to bend it straight cold, but it will likely break.(wear safety equipment, use a vise, and plan on moving to regrinding when it breaks) Regrinding the tip shorter can be done with limited tooling and time, but is still quite a bit of dirty and dangerous work. You may end up with a shorter, but still useful knife. Ask yourself how much you're willing to invest to save the knife. It's probably not worth it, unless you have time to kill, and some knowledge and tools. Be safe!
I found a random orbital sander with 240 grit works well, when you need to remove a lot of material faster. Have to keep rinsing of stone and wiping off the paper. Obviously don’t use the sander around the sink or a container of water. Just wipe the excess water of stone before sanding. The stone clogs up fast, so a lot of rinsing.
The flattest object known to mankind is a democratic senator, so X-Ray Nancy Pelosy’s head and use the flat side. Lasers are jealous! Careful, there are no spare spots to be found, it just keeps the brain from rolling around and falling.
Excellent job with information. One of my whet stones has wear in the middle area, since this is the primary area I use when sharpening. The diamond stones do not recommend using water. Lapping fluid is used. So what is used in this case? Is it ok to use lapping fluid on a whet stone for the flattening process?
if you're moving your flattening stones 30-50% off the ends of the object you're flattening and working in circles, the act of using the stones will maintain their flatness pretty well.
use a sheat of 6 mm tempered glas, water and silicone carbide, the carbide will bite into the glass, when you flatten the stone, turn the stones 180 dgr. every once in a while. i use this to flatten stones, it is extrtemely fast and efficient ;-)
I have Naniwa (A-102 and A-103), and noname chinese (Taidea) flattening stones. All of them tend to hollow out in the middle (Naniwa slowly, Taidea almost instantly). What is the easiest solution to flatten the flattening stones? Lay down some coarse sandpaper, and give them some rubbing? I have chinese diamond stone as well, but I don't know how fast they would destroy it to the bare metal. (Wrap the diamond stone in sandpaper, then flatten the flattening stones on it? :D )
Hey, I don’t know if you still read these comments but I was wondering if a fixing stone is really necessary. I have a King 1000/6000 grit combination and I have a lot of metal particles ingrained. Would a fixing stone help? And if so which one would you recommend?
Hi. I got one, surface did not last too long when i was correcting blade on knife.Bigger problem is that "diamond" plate is glued on plastic board which is really not flat.So it is worth of 2$ but do not expect you will get something special.
Beginner issue. When my stones are flattened (with diamond plate) I can feel the longer sides higher than the rest of the stone. Is probably due to the chamfer/trim corners in a wrong way?....too low angle....?...too high.....? thanks.
One thing not said here is that when you flatten you want to also round up a bit all edges of the stone - on the side you just flattened, obviously. That's when using sandpaper is less helpful - using an abrasive plate at about 45* on the edges of the stone works well, but trying to grind the stone at 45* on sandpaper will not feel very consistent or comfortable.
I recently started buying the Shapton Glass Ceramic stones, but the company recommends to only use the Shapton brand lapping plates (which are super expenisive). Do you think using any other lapping plate/flattening stone is safe to use on these ceramic stones without damaging them?
@@_wormlet Following the advice of another youtuber, I use my Shapton Glass 500 to flatten my 1000. Furthermore, I use my 1000 to flatten my 4000. Seems unorthodox, but it works. That being said, these ceramic stones seems to wear quite slowly, so flattening isn't a chore that you have to worry about all the time.
atoma sells the diamond grit attached to sticky metal sheets that you can place on any surface he got a piece of metal milled pretty cheap and then bought the Atoma diamond grit seperately
In the FAQ section of the Shapton website they say about the use of sandpaper that "abrasive paper can leave a stone clogged, with the result that the blade slips and it is impossible to sharpen it". Is it true?
i think they are going on the extreme side, and wanting you to buy their insanely pricey flattening plates. if you truly want to spend money on a diamond plate, i use the Atoma 140 burrfectionstore.com/collections/accessories/products/atoma-diamond-sharpener
You didn't mention the best way to do it, a flat plate and some sand. The cutting action is totally different, much faster, is worlds better for lapping something flat, and will flatten anything. I prefer porcelain tile for the flat as it is much harder and wear resistant than glass or pretty much any stone, and dirt cheap! Silicon carbide is better than sand but sand will work just fine. The only downside is it creates a much bigger mess, so do it on a sheet of cardboard to help contain the mess.
Damn, honestly, that shapton pond is really nice. i would buy it. Years ago, when the economy still had some semblance of prosperity i mightve been able to throw money away on it. Just for bragging rights...
So on all of the stones I was Blessed with there is Black build up or reasadew ! I have sanded.ground it off what am I doing wrong or has the stones had something incorrect done to possible one the biggest and spread around in stone box, I maybe Helpless
soak them before use but i would not recommend actually storing them in water. I've heard it may degrade the structure of the stones so to be on the safe side, I wouldn't do it
I agree. Arkansas stones have been widely used quite effectively and were the primary means for sharpening for years in the US. I would like to see this too.
They’ve largely been left in the dust because Japanese waterstones cut so much faster. Every extra stroke required is another potential problem if your mind wanders.
I feel the need to point out that the Shapton diamond plate has a glass back, this is because the glass will stay completely flat. if it were just the metal, it may warp over time. this is important because the glass is what makes the Shapton so reliable. It is part of the utility of its design.

Hey, I just bought a whetstone kit to try and sharpen some old kitchen knifes I have.
We have a fairly nice chefs knife that has never been sharpened, and at some point developed a nasty bend at the tip.
The knife itself is fairly straight, but starting from maybe an inch from the tip there is like a 20-30 degree bend.
I tried just bending it cold in the opposite direction, but it won't budge.
Im considering using a blow torch to try and heat it up and then straighten it. Then try and re heat treat it afterwards. (Im not sure if it is heat treated, but i think it is based on how flexible it was without deforming, ill check with a file before i start)
Do you have any recommendations or suggestions? Or is it a dumb idea that i should not even bother trying.
Thanks for the help. I really enjoy your videos btw. I recently stumbled upon your channel and i find them extremely interesting, informative and well made.
Heat treating is no small matter. The temps involved will destroy any handle material, so you can plan on removing/replacing the handle before you even consider heat treat, then there's the matter of temperature control, particularly if it's a stainless knife. Simple answer, don't, the chances of success without a lot of specialized equipment are pretty low. You could try to bend it straight cold, but it will likely break.(wear safety equipment, use a vise, and plan on moving to regrinding when it breaks) Regrinding the tip shorter can be done with limited tooling and time, but is still quite a bit of dirty and dangerous work. You may end up with a shorter, but still useful knife. Ask yourself how much you're willing to invest to save the knife. It's probably not worth it, unless you have time to kill, and some knowledge and tools. Be safe!
I found a random orbital sander with 240 grit works well, when you need to remove a lot of material faster. Have to keep rinsing of stone and wiping off the paper. Obviously don’t use the sander around the sink or a container of water. Just wipe the excess water of stone before sanding. The stone clogs up fast, so a lot of rinsing.
And turn the paper so the holes don’t line up with holes in sander, so you aren’t sucking in water.
Oh and it wears out paper fast. Make sure to keep the sander moving. Then finish off with cleaning rubber stone and or one of you great above methods.
I like my stones like I like my earth, flat.
Nice joke
LMAO! You're some kind of special.
Stones are just a ploy for the government to poison us.
That’s hilarious, but only if you’re kidding 🤔
The flattest object known to mankind is a democratic senator, so X-Ray Nancy Pelosy’s head and use the flat side. Lasers are jealous! Careful, there are no spare spots to be found, it just keeps the brain from rolling around and falling.
Wet sand paper is the best.
Could you use another generic whetstone with a low grit to flatten your higher grit stone?
Yep
Excellent job with information. One of my whet stones has wear in the middle area, since this is the primary area I use when sharpening. The diamond stones do not recommend using water. Lapping fluid is used. So what is used in this case? Is it ok to use lapping fluid on a whet stone for the flattening process?
Use water so the water stones do not get damaged
@@BurrfectionWill do. Thanks.
if you're moving your flattening stones 30-50% off the ends of the object you're flattening and working in circles, the act of using the stones will maintain their flatness pretty well.
use a sheat of 6 mm tempered glas, water and silicone carbide, the carbide will bite into the glass, when you flatten the stone, turn the stones 180 dgr. every once in a while. i use this to flatten stones, it is extrtemely fast and efficient ;-)
I have Naniwa (A-102 and A-103), and noname chinese (Taidea) flattening stones. All of them tend to hollow out in the middle (Naniwa slowly, Taidea almost instantly).
What is the easiest solution to flatten the flattening stones? Lay down some coarse sandpaper, and give them some rubbing? I have chinese diamond stone as well, but I don't know how fast they would destroy it to the bare metal. (Wrap the diamond stone in sandpaper, then flatten the flattening stones on it? :D )
Hey, I don’t know if you still read these comments but I was wondering if a fixing stone is really necessary. I have a King 1000/6000 grit combination and I have a lot of metal particles ingrained. Would a fixing stone help? And if so which one would you recommend?
The King nagura stone helps
Thoughts on eBay or aliexpress diamond flattening plates? I have a 400 grit one coming for 2 dollars and it looks half decent lol.
Hi. I got one, surface did not last too long when i was correcting blade on knife.Bigger problem is that "diamond" plate is glued on plastic board which is really not flat.So it is worth of 2$ but do not expect you will get something special.
Beginner issue.
When my stones are flattened (with diamond plate) I can feel the longer sides higher than the rest of the stone.
Is probably due to the chamfer/trim corners in a wrong way?....too low angle....?...too high.....?
thanks.
One thing not said here is that when you flatten you want to also round up a bit all edges of the stone - on the side you just flattened, obviously. That's when using sandpaper is less helpful - using an abrasive plate at about 45* on the edges of the stone works well, but trying to grind the stone at 45* on sandpaper will not feel very consistent or comfortable.
He said the last one was a Shap Tip. It appears to do the best job, but I can't find it anywhere online. I wish she had spelled the name.
220 for all stones?
I recently started buying the Shapton Glass Ceramic stones, but the company recommends to only use the Shapton brand lapping plates (which are super expenisive). Do you think using any other lapping plate/flattening stone is safe to use on these ceramic stones without damaging them?
How did you flatten yours? Just bought a Shapton Glass 1000 and can't afford another majorly expensive diamond plate
@@_wormlet Following the advice of another youtuber, I use my Shapton Glass 500 to flatten my 1000. Furthermore, I use my 1000 to flatten my 4000. Seems unorthodox, but it works. That being said, these ceramic stones seems to wear quite slowly, so flattening isn't a chore that you have to worry about all the time.
Wait, how did you make that atoma? Can we buy one?
Booch 4 Snooch agreed. I’d love to know more on how he did this.
atoma sells the diamond grit attached to sticky metal sheets that you can place on any surface he got a piece of metal milled pretty cheap and then bought the Atoma diamond grit seperately
Does sandpaper work for any grade of whetstone? Even fine ones like a 12000? Thank you
Yes but it will feel really sticky, so rinse often
In the FAQ section of the Shapton website they say about the use of sandpaper that "abrasive paper can leave a stone clogged, with the result that the blade slips and it is impossible to sharpen it". Is it true?
i think they are going on the extreme side, and wanting you to buy their insanely pricey flattening plates. if you truly want to spend money on a diamond plate, i use the Atoma 140 burrfectionstore.com/collections/accessories/products/atoma-diamond-sharpener
How often you flatering the stones?
Vasilis Manatos ideally after every use.
You didn't mention the best way to do it, a flat plate and some sand. The cutting action is totally different, much faster, is worlds better for lapping something flat, and will flatten anything. I prefer porcelain tile for the flat as it is much harder and wear resistant than glass or pretty much any stone, and dirt cheap! Silicon carbide is better than sand but sand will work just fine. The only downside is it creates a much bigger mess, so do it on a sheet of cardboard to help contain the mess.
Thanks for the tip, I have a porcelain tile and sand, never thought of that one, but will give it a go.
My instinct was for wet/dry sand paper on my granite counter top, but I just wanted to see from someone who had tested it. Thanks!
Damn, honestly, that shapton pond is really nice. i would buy it. Years ago, when the economy still had some semblance of prosperity i mightve been able to throw money away on it. Just for bragging rights...
it's pricey stuff and not essential to own
You should totally do one on whetstones from wish
So on all of the stones I was Blessed with there is Black build up or reasadew ! I have sanded.ground it off what am I doing wrong or has the stones had something incorrect done to possible one the biggest and spread around in stone box, I maybe Helpless
You forgot the three stone lapping method. Where you lap three objects together and get a perfectly flat surface
Should I store my stones in water?
soak them before use but i would not recommend actually storing them in water. I've heard it may degrade the structure of the stones so to be on the safe side, I wouldn't do it
@@jd223_ awesome thanks. I saw people say soke them for like 48 hours. Was wondering why not just keep them there.
Question: Will you review and use Arkansas sharpening stones? THANKS!
I agree. Arkansas stones have been widely used quite effectively and were the primary means for sharpening for years in the US. I would like to see this too.
They’ve largely been left in the dust because Japanese waterstones cut so much faster. Every extra stroke required is another potential problem if your mind wanders.
once in a while take a brick and reflatten the sidewalk too so your reflattening stone gets reflatten evenly
