[@patjackson1657]

I did my best to get the gear you recommend. The Trend 300/1000 I found locally, and the Shapton stones closest to the grits you advise are a 5000 and a 12000. These are replacing my water stones that after 30 years of use and abuse are finally done for. Since I don't have a grinder or a Tormek, I added a 140 diamond Atoma to bring my badly abused blades back to shape. Many hours later, I have 1 plane performing better than it ever did before. The other 2 are close behind. Thank you very much. At 71 years, I will never catch up to you KZbin heroes, but I will enjoy the chase!

[@leadingedgeknifeandtoolsha4128]

i dont sharpen my chisels that often, but i sharpen chef knives almost daily, and i have something you might be interested in. it is called a sink bridge. they can be found on amazon for $30-$40, and they work amazing. you can uses them over a sink, as you can guess, or as i used them over a bucket of water. the sink bridge is the greatest sharpening tool i have ever found. it makes life so much easier. no more squirt bottles, just reach down and grab a little water with you hand, and clean up is just drain the water out of the bucket. no more weird clay stuff (swarf) on you counters or bench. i will say, i do prefer the ha no kuromaku shapton over the glass shapton but that is personal opinion. i like your videos, but that 3 1/2 minute dovetail video is your finest work. i have watched it about 10 times now, and every time it seems like magic, keep up the good work

[@RobCosmanWoodworking]

Tried it and I don’t like it in a woodworking shop. Wood and lots of water dont go together and you only need a little spritz bottle not a bucket full of water. Most woodworking shops dont have sinks and the first time you spill you bucket of water in your shop it is not fun. I prefer a little spritzer bottle. I just dont think that method translates well in a wood shop

[@leadingedgeknifeandtoolsha4128]

Rob, my first purchase from your shop was your sharpening system. Smartest tool purchase decision I ever made. Even with mediocre starter tools I was able to get the kind of results in my woodworking I had been hoping to get for years and years. As I’ve added better quality tools, I’ve been able to get maximum performance from them because I know how to sharpen them right and keep them sharp. Your sharpening system isn’t “original”, but it’s tried-and-true and a guy will save a lot of money and time if he just buys your system components right away. Thanks again.

[@ronin4711]

Rob I love your videos because they are all no nonsense and very useful information for the novice and for the profesional also. However, and I emphasize on however, your references are good but,very expensive! Starting with your dovetail saw, which is great but the most expensive ever. Also, sharpening stones: If you are a novice and you are not sure if you want to invest "big", unless you are rich and bored and looking for a hobby, there are a lot cheaper alternatives to look for. For the pro, I'll say, go for it because you already tried probably everything and it makes sense.

[@RobCosmanWoodworking]

We have to disagree on something. Having been down the road of “buy cheap first” I now advocate to buy the best, cry once! If you are not sure you want to get into the craft then do some more investigating or find a friend that does it or a guild. Buying low cost/low quality will do more to discourage than promote. The used tool market is good so if you decide to hang it up, sell your good stuff for most of what you paid and move on. My advice for what it’s worth. Thanks for commenting.

[@ronin4711]

@@RobCosmanWoodworking Rob. First, thanks for your quick response. I totally disagree! What if I’m not sure what I want to get into? I’ll cry forever for a bad investment! Have a little mercy on those poor people! You can still buy decent tools to start with and not being in “big” investment if you’re sorry. I made once a big mistake, I went to night school for HVAC and refrigeration, have nice Diploma but could never pursue the trade because as apprentice I couldn’t pay my mortgage for the home I just bought! I thank God that I didn’t invest in tools for that! And that’s a lot of money! I Imagine that I would have been still crying now 26 years latter. As I mentioned before, if you’re a pro, by all means, buy the best, cry once! I mentioned some time ago, that your videos are a bit too rich for some “mere mortals”... Good intentions but you sometimes miss the target. Continue with your work, it’s all in good intent, I’m sure...

I've used the Shapton system for years. Expensive, but great results.

[@RobCosmanWoodworking]

I have the same experience

[@james.tupper]

I use this same setup and can attest to the Trend being out of flat. Mine is cupped to the point where it's totally unusable for anything but narrow blades. I use a honing guide and the Trend is nearly useless with it because it grinds all of my blades with a negative camber / laps my stones with a reverse cup. The time I have to spend trying to correct its unevenness is just not worth it at all. If you are good a freehand sharpening, then you'll just have to remember to learn the shape of your Trend plate and compensate for it. I love this method of sharpening, but just don't rely on the Trend plate for it. Spend a little extra for an actually flat stone.

[@CandidZulu]

I always said broom and dustpan are the two most important tools in any shop. Personally I work a lot with small mechanical things, such as firearms. If I drop a part on the floor, it is more likely gone forever if the floor is untidy. And general neatness and organization are key to any good work. But after that I would say sharpness is very high on the list. To flatten an oil stone, take a concrete garden slab, as used for foot paths. Some are machine made and very flat. Pour some Silicone Carbide coarse grit on one side, and add some water or oil. Now rub the oil stone in this mess until flat.

[@davida369]

The spritz bottle, I use old supermarket cleaner spray bottles, I always remove the top and make sure the dip tube is in the front of the bottle when I reattach the top so when held forward the end of the tube is in the liquid.

[@RobCosmanWoodworking]

That works too. I always got frustrated when the liquid was running low and tilting the bottle the tube couldn’t suck up anymore water. Call me lazy but I hated filling up that bottle more often than I absolutely had to!!!!!

Fantastic information

[@spagati]

For flattening my stones and metal plates I use the Shapton 空母　(aircraft carrier). For the mirror side of my blades and chisels I use metal plates, first with silicon carbide then diamond paste. The metal plates I also maintain flat with the Shapton 空母. The mirror side I have to do it only once for the whole life of the chisel or blade. The burr comes of easily just by polishing the bevel.

[@RobCosmanWoodworking]

So what micron size is your diamond paste? The smallest made is around 1.5 micron but the Shapton 16k is .92 microns. Your system will absolutely work, but I think having a 16k stone that has finer abrasive and is ready to go is more convenient and gives a slightly better polish

[@spagati]

@@RobCosmanWoodworking The advantage is the flatness of the metal plate, it stays longer flat, so you can get a flat mirror side, with no distorsion in the reflections. With the stones I can’t get a flatness like that. Diamond paste you can get till 0.1 micron, I use 1.0 micron in the end, which sufficient for a very fine cutting edge.

[@darrylportelli]

Hi, any idea of the difference between the glass series from Shapton and the Ha-no-kuromaku line (the 12K cream stone) ... the online wood work shop I order from in the EU only has the Ha-no-kuromaku line ..... Also any idea how the Naniwa 12K compares to the Shapton 12K ? they are almost identical in price ... cheers

[@SarcastSempervirens]

That big steel ruler you showed in the end has the perfect hole on one end to drive a screw through the end part of the big rubber holder and simply attach one end of the ruler on the screw and hold it on the opposite end and it's not going anywhere. Cosmanise the holder! :D

[@robohippy]

I chatted for a while this morning, with a tech at DMT. They now have 4000 and 8000 grit diamond plates. The 16000 is one I haven't been sold on yet. In particular because one British guy, Matt somebody, commented that his red rouge polishing compound was 16000 grit. In trying to find out polishing compound grits, apparently there are no standards..... ARGH!!!!!!

[@paulkarch3318]

Generally what is the lifetime of the Shapton stone? I noticed that it needs to be flattened each time you use it. I know it depends on how heavily it's used but some idea would be useful.

[@dgt79]

Thanks for all the woodworking lessons Rob, I’ve learnt a lot from you. I’ve seen other woodworkers prefer Shapton Pro stones and was wondering if you ever considered those stones. From what I’ve seen Pro stones have more thickness while Glass ones are slightly better for harder steel

[@RobCosmanWoodworking]

They are good stones. Tried them but i prefer the glass stones. I think the binder is better and the abrasive cuts faster than the pro

[@fernandocastillo8187]

Hello Rob. I'm planning to buy the combination you recommend In this video. Tren Diamond + Shapton. However I have read more than a few reviews arguing that the 1,000 side of this diamond plate often is not flat. Have you ever encounter this problem? I know that you can send back a defective product and ask for a replacement or a refund but when you buy your tool what you want is to use them. I kind of know what your answer would be but........ What would you recommend?

[@christianestrada5362]

Thank you for sharing. That shapton system really looks nice! I'm thinking about getting the Trend since it's not as expensive but the honerite would eventually add up too. Not having to worry about rust is a really attractive feature on the Shapton.

[@RobCosmanWoodworking]

If you just keep your dimaond stones wiped down and dry after each use you will be OK. The Honrite is a safty feature in case you every foget to dry off your diamond stone. It lasts a long time

[@craiglomax9913]

The cost for the honerite is very low as it will make enough to last a hobby user more than a year

[@ef2b]

I already own a DMT Dia-Flat lapping plate, which is 95 micron / 160 mesh grit. Is that too coarse for lapping the Shapton 16000 plate? It's supposed to be flat to 0.0005". I sharpen freehand, producing a convex bevel. This method doesn't work well on most water stones because of the possibility of catching and gouging the water stone. Is the Shaption 16000 harder so that gouges are less likely? Unfortunately, catches just happen. Maybe not often, but they happen. I have a #10000 Sigma Power stone that I use on occasion, but usually stay with oil or diamond and a strop, so I'd like to try the Shapton 16000.

[@tompossessed1729]

You probably ain't checking on this video but this is the only video on sharpen stones. My question to you is thoughts on the Norton and spyderco ceramic stones because they grit up to 2000 to 8000 and don't wear down like the Sharpton ceramic water stone

Hey Rob, thanks for the video! What are your thoughts on the older shapton synthetic stones from the 2000's? I have the 1000, 5000,8000, and 12000, along with the diamond lapping plate from back then. I like them a lot but wondering about improvements that could be added. I think they made a 30,000 grit one to, but the price was crazy.

[@BGP369]

Same as with cutting edge (pun!) computer components over mainstream - 5% performance increase for 3x the price. For those with the money to not worry about this, go for it. For the rest of us, its a no brainer to go with the lower cost option while not going too cheap as to have it need replacing often.

[@rostoi6985]

Hello, thanks for sharing this knowledge. I am wondering if thé ppl saying that thé 1000 is enought are really wrong. I also believe you are right. 1000 is enought for most of thé planings (flatening a board, putting a board to size, etc.) and 16000 is good for thé smoothing plane. May bé thé ppl you quoted don't use machins at all and that They Can not share your point of view as it seems you are using machins to make boards flat for example and mainly using planes for thé finishing tasks ?

[@spaaarky21]

Is that explanation of grit @3:20 right? If you split 1 square inch into 1000, each section would be juuust under 1/32" by 1/32". Even the particles on 80 grit sandpaper don't seem that big.

[@buddythompson5284]

So, just to recap, using the Trend 300/1000 diamond stone and a 16000 Shapton water stone gives really good results, but using all Shapton stones with a Shapton flattening stone gives better results because the Shapton flattening stone provides for flatter surfaces than does the Trend stone, is that correct?

[@filipkellner9776]

Hi Rob, i have your "older" recommended set eith Trend diamond and 16000 Shapton. I was looking after 500 Shapton lately to give it a try and i was surprised they now have Soft bond or Hard bond from each grit, to be used on different types of steel.

Rob, I see thart you use Honerite as a lubricant. Since it is impossibble to me to get this in Argentina, I am wondering if I can just replace it with water plus a corrosion inhibitor, like the one people use to prevent corrosion in boilers and things like that. Has oHnerite special aditives, that make its use mandatory, or it can be substituted by a second best alternative?

Question: why Trend instead of, say, DMT?

[@alexroge6495]

The trend plates really aren’t flat enough for chisel backs. They are no different from all the other Chinese made dia plates. I’m sure the shapton is great, but a much cheaper way to get truly flat is by useing lapping flim on a granite surface plate or float glass.

[@bigbattenberg]

Just recently bought the Trend diamond stone and was very unimpressed with how out of flat it was. Visible bow to the eye so I returned it. Kind of stuck and don’t know what system to use for sharpening without spending and arm and a leg..

[@RobCosmanWoodworking]

We quit carrying Trend about a year ago for that same reason. Went to the original manufacturer, better product.

[@RobCosmanWoodworking]

Trend has stated tolerances, contact them for a return. Most were good but the hassle of testing every one was ridiculous. You may have just been unlucky.

Go with Shapton, either Pros or Glass. For flattening stones ONLY, Atoma 140 or 400 grit is the best choice. I have the 400 grit one, flatten my shapton pros daily and are super flat. 85 euros only

​@@RobCosmanWoodworking Rob, what is the name of the original manufacturer? And if you qui carrying Trend does that mean that you would no longer recommend the Trend Sharpening Kit with the double sided 300 / 1200 grit diamond sharpening stone? I was considering buying the Kit until I noticed this post. Med Vänliga Hälsningar

This is great info,but to be honest,for someone like me ,that don't use plane often,all these recommendations are way too expensive, after checking the prices here in Canada. Maybe you can do recommendations for more economic options. Thank you again.

[@cbat09]

Do you use the ruler for the back of a low angle (bevel up) plane blade?

[@RobCosmanWoodworking]

Yes!

You just saved me $500!

[@leebronson6865]

Woooow, thanks dude! I learned a lot here. But Why there are so many black scratches on the surface of the whetstone when I use my new 6000 whetstone to sharpen knife? Even if I rub it with my hand and water, they won't go away completely. I had to scrape it with a flattening stone. Does that mean the whetstone is of poor quality? Am I being cheated by the merchants？

[@RobCosmanWoodworking]

The black scratches are metal being left behind by the knife. The stone wears, but the knifes wears faster.

[@leebronson6865]

​@@RobCosmanWoodworking Really appreciate your help. So I don't have to worry about the scratches and just use flattening stone to remove them, right? That doesn't mean the sharpening stone is bad?

[@RobCosmanWoodworking]

That’s correct

[@vane5736]

I have been trying to sharpen my plane iron with some waterstones. It grinding off metal but not getting sharper. There is no burr. I'm using a honing jig on the 400 grit stone.

[@RobCosmanWoodworking]

Thats not good. Watch my video on how to sharpen plane blades. You should not have to start with such a heavy grit as 400, it will leave deep scratches that you have to remove. Watch the video. Even if you dont want to freehand, follow the steps with a jig

I had similar problems for a long time until I changed a couple of things. First, make sure the back of the iorn near the edge is truly flat all the way across the width of the iron. Using the ruler trick helps by limiting the amount of the back you have to flatten. Secondly, whether flattening the back or honing the bevel, don't press down on the iron any harder than you need to for it to remain in contact with the surface of the stone. I used to press down hard trying to get the stone to cut faster. That doesn't work and it takes only a very small inconsistency to ruin the edge you just cut. Let the stone do the cutting by itself. You're just guiding the blade over the stone.

Dilemma, I found the funds for a new plane, I have a 5 1/2 woodriver, do I buy a low angle block or a 3/4 shoulder plane? I own a junk Stanley block...

[@RobCosmanWoodworking]

Low angle block. It will get much more use than the shoulder plane.
