    That's a tough one. I've had the Nova for a couple years, but the Harvey for only a couple weeks. My favorite bit about the Nova was the full variable speed without changing belts, and the cool digital options in the computer. But the Harvey has a range of 90RPM to 4300RPM with a single belt setting. The only reason to ever touch the belt is if you want to go slower than 90RPM, which I don't see a need for very often at all. The Harvey is a more robust machine with a heavier bed that's a single piece, while the NOVA is split in the center of the bed. The Harvey also has a better fit and finish. Both are nice lathes that will get the job done. So you have to decide between the digital options of the Nova, or the better overall quality of the Harvey.

    I was a Sr. Engineer at a plant that made diamond coated grinding wheels and some other things. You’re absolutely right about such fine grits being impossible to use with the nickel bonding process. I also question the need to use grits finer than about 800 to sharpen wood working tools. How sharp is sharp enough? I’m often guilty of overkill but 800 + a leather strop will get ya close enough for most chisel and plain work.

    Nice to hear from another source :) ... As for grit, I usually sharpen with a 1000 grit diamond stone, then a leather strop and paste. For smoothing planes, or paring chisels that need to be REALLY sharp I will use a 8K or 16K grit ceramic stone. Not because the strop and paste won't get me there, but because I can move the tool across the stone faster than on leather, which can only be stropped in one direction.

    Thanks for the explanation. I switched to ceramic stones for finer grits a while back as I just never liked the results finer diamond stones gave me. I don’t use strops for chisels anymore as it can round over the back which can cause issues when you want to reference against the back of the chisel blade such as cutting down the wall of a mortise or flush cutting. It’s a small thing that isn’t a huge issue either way, I just got into the habit of going to the ceramic stones instead of a strop.

I found myself preferring an Atoma 1000 or 1200, and transitioning to Japanese whetstones at 3,000, 5,000, or 8,000 grit as needed. For any higher polishing, I go to a leather strop and diamond paste. Looks beautiful and performs well.

    I bought the Trend kit on your recommendation and agree it's the sweet spot for woodworking tools. I've also used it to do some other blades that needed some love. The 300 flattens fast, and the 1000 is perfect for getting a burr quickly from then on. The strop does plenty from there (heck, some woodcarvers ONLY ever strop with a little compound). I'll probably end up with some high-quality waterstones for sharpening Japanese kitchen knives, so we'll see if one ends up near the workbench eventually.

    A friend of mine bought the DMT 8000 grit plate to try as the first grit he'd use on a straight razor. It cut way too quickly for that purpose so I bought it off him for my woodworking tools. It gives a beautiful mirror shine to my bevels. The problem is it actually tends to Dull my edges! You can see artifacts from the manufacturing process that have Definitely done exactly what you said and compromised the flatness of the cutting surface. My edges, constantly transitioning from low spots to high spots are significantly less sharp than they started straight off my 1200 grit plate. I've got a full set of DMT plates and I love all of them, except the 8000.

    Devils Advocate: the 4000 & 8000 grit DMT stones are about all I ever use going down to 1000 only if I can see damage. 10-15 strokes each grit. Feel for even burr then flip to take off burr. I admit not knowing the manufacture process but what works, works. I do not believe 8000 on diamonds is as fine as 8000 on my old Norton water stone which is why I always thought others switched to other stones.(edit: been using same stones heavily for 7-8 years as am mainly HT worker.)

    Somewhere I also heard it takes a while to “bed in” higher grits as there some course ness in manufacturing that needs to wear off. This is the case with my 8000 as the corners (which I rarely use) feel grabbier. Again, this is experience based not research.

    I find that when it comes to sharpening, experience is 80 percent perception, 20 percent reality. A couple guys in these comments swear by their 8k plates, and a couple claim the opposite experience. Which is reality and which is perception? Who can say. It is true that what works, works. But I know someone who claims only oil stones work for him. Another guy commented above that he gets great results from stropping AFTER an 8k stone, even though the strop is coarser than the stone. The funny thing is, they are all right! If it works for them, who can argue with it:)

    Other kinds of Diamond plates are available that address the issues you (rightly) bring up here. Naniwa makes Resin bond Diamond stones from 400 to 6000 grit that perform like waterstones, but cut and stay flat like diamond plates. They are flattenable to .0001" using silicone carbide powder on glass and hold that flatness for a long, long time. Very expensive, though ($160 or more). All the convenience of diamond with the versatility of waterstones. There are also Venev diamond plates that are similar and not quite as expensive, but hard to find as they are Russian made.

Super shiny, super curly wood shavings all day long. once they stop shining, I hit the strop for a few passes and its right back to shiny curls.

    It seems to be a hugely contentious argument with woodworkers, and no doubt the superfine stones can give an almost perfect edge, but how long does it last, what's the point if a few blows of a mallet has reduced the edge to the next grade down? I've been experimenting with automotive paint rubbing compound and metal polish on MDF boards for final finishing an edge which seems to give good results. I hate to say this though, but I always look back at the fine woodworking achieved by our forefathers without all this fancy stuff and think...it's more to do with skill and patience.

    In my experience, the sharper the edge, the faster it dulls. There is a limit to how much the bevel and back of a blade can achieve the so-called infinite point before it becomes brittle, breaks, and dulls. I think I remember hearing Cosman say, he sharpens his planes every few minutes. That's because he sharpens to 16,000 grit. Spending that much time sharpening would dive me nuts. Paul Sellers, on the other hand, sharpens to 1000 grit, and then strops, which is what I do, and sometimes I don't bother with the strop, which really doesn't add sharpness as much as smoothness and polish to the bevel. One of the things I've learned in 50 years of playing with wood and tools, is it's really easy to overthink, and by doing so, miss the fun and the point. Pun intended.

That makes the decision easy. I normally go for the cheapest solution that works. I know, all good diamond plates are expensive, but they´re convenient to use and always flat. That makes it worth it for sharpening but polishing is something different, because not very much material gets removed. The strop isn´t flat but it doesn´t affect the result. I just haave no use for ultra fine diamond plates.

It creates almost none of the black carbon slurry which I see from the other plates. I sharpen with the aid of a 10X loupe so I can inspect the surface finish and edge. I do see a degree of surface polishing using the loupe, but not much. Pehaps I have worn out the 8000 grit plate. I see much more polishing effect stropping with buffing compound on MDF. I think Rob Cosman uses a 16,000 grit stone btw.

    James, I ordered a 3000/8000 whetstone after watching this video, so at the very least I'll be able to compare. At the risk of being a tads controversial, something I have been doing for a while now is using a felt pad in a Dremel for the final hone. You'd think it would roll the edge, but I place the blade on a block of wood level with the end, and hone with grey buffing compound. It gets a mirror finish in seconds. My test for sharpness is to hold a sheet of printer paper in finger and thumb, and advance the blade into the paper at 90° and a couple of inches (whoops! I mean 50mm) from where I am holding it. If cuts straight into the paper I call that job done. I've tried this same trick with a set of carving chisels that I paid about a $100 for, and it rolled the edge to the point where you could safely drag it across your skin without cutting yourself. I guess if nothing else I can use it as a test for rubbish tools.

    Interesting opinions here. I currently own couple DMT diamond plates, most fine of them is extra fine (1200 grit). After that I use 1200 wet sand paper on glass. I see the polishing effect there. So quess the similar sandpaper (1200 grit) might have finer particles, after paper is used couple of times ? With sanding paper burr strip is detached from blade edge. I use leather strop after this. **** As magnifying loupe, I use 1.25" telescope eyepiece in "wrong" direction. Maybe I need to still wait a while before ordering finer stones, I would prefer also stone that works on sharpening carving chisels....

Any machinist worth his salt will tell you that machining can't make anything "flat". That is the job of the surface grinder. Which, by the way, is commonly used to grind to tolerances of 50 millionths of an inch or greater. You know as well as I do that a well tuned hand plane will allow you to hand plane something to the thousandth of the inch. Not busting your chops just giving information.

    I realise the Trend combo stone you show in the video is aprox 300 grit on one side & 1000 grit on the other. I also am aware of the premium reputation these Trend diamond plates. For my purposes I require only one sided stones/plates. No need to go into why, but the other side would never be used as per my sharpening system. Hence I use DMT DiaSharp one sided diamond stones/plates that as far as I have been told are of similar quality as that of the Trend products. The DMT DiaSharp are heavy nickel plated mono-crystaline plates considered to be a premium product like the Trend. They are not the cheap perforated poly-crystaline plastic versions. Admittedly I have had mixed results (ie: flatness tolerances, uneven coating & surface scratches) always rectified by the manufacturer or seller to my satisfaction. I have 3 stones/plates I use regularly; 320 grit, 600 grit & finally 1200grit. The question I have for you is this: Do you think there is an appreciable difference between the 1000 grit & 1200 grit that I should be concerned with the issues you mentioned about ultra fine stones/plates & the adhesion? I too switch to ceramic & then strops after the 1200 grit. I suspect the same electro coating process is used for both the Trend & DMT products but do you think or know if the extra 200 grit would be manufactured differently than the 1000 grit Trend? I would just go with the Trend but as I mentioned, one side would go to waste & I would have to purchase 2 of the same stones to allow for the use of 300 grit & 1000 grit. I also require a medium grit of 600 for my applications. Three diamond stones/plates then ceramic followed by a leather strop with polishing compound. If required, I will also use an extra coarse diamond plate (not part of my set up) or a coarser Aluminum Oxide or Silicon Carbide stone to remove chips or re-profile. If the item permits, I will use my Tormek T8. I also have several other bench stones & guided fixed angle sharpeners. It's difficult to explain why I can only use one side of the plate but please believe that is my only option for this system unless I want to spend 15-20 minutes turning over & re-installing the diamond plate from 300 to 1000 grit between sharpening steps each time, otherwise I would just go with the Trend but even then, I would not have the necessary intermediary 600 grit I have with the DMT plates. Thank-you for any input, knowledge & or experience in this matter. I suspect there is little to no difference between the 1000 grit & 1200 grit as far as the manufacturing process goes but he more you know & all that. Cheers.

    @@green_building James did a really good job of explaining it. Here's my best (short) explanation. The diamond particles are embedded in a nickel matrix that doesn't 'give'. Whatever is there does not move. If there are a couple pieces of diamond sticking higher than the rest, they will leave scratches that are simply impossible to get rid of without taking more of the steel away from the blade you are trying to sharpen. Everyone of those scratches degrades the edge so that it starts to deteriorate faster than it would otherwise. Of course, you can wear away that steel to get rid of the scratch, but that diamond particle is still there so bingo-bango the scratch is back. I realise that is a way oversimplification of what happens but beyond a 30 page article and pictures/videos I can't think of a better explanation. ( I probably will about an hour after I post this, but there ya go.) For proof of waterstones being able to produce a better surface, just take the highest grit diamond stone (8000 as far as normal humans are able to find) and the same grit waterstone, hone a blade with both and look at the scratch pattern with an eye loupe. The difference is amazing. Now, do you NEED that level of surface to do woodworking? Simple answer is no. Just look at Paul Sellers's work for all the proof you need. I use waterstones because I like the way they work and the surface I can get with them. Could I do the same work without them? Almost. There are times when I need the absolute best edge I can get, and that ain't happening with Diamond stones alone. Both Diamond and waterstones take a bit of skill to get the best from them, waterstones being the harder of the two, IMHO. Strops are another device where everyone has a different opinion. Mine is that I use strops sparingly for initial sharpening, but I'll refresh an edge with a strop while using a tool, especially chisels. Plane blades, I'll just go back to the stones for a touchup since you already have to partially disassemble the blade anyway, unlike a chisel where you just have to turn to the strop, hit it a couple times and back to work in about 4 seconds. I worked with metal my whole life and I can tell you there is a lot more to it than just being shiny. Parallel, flatness, wear resistance, hardness, toughness, etc. These are all aspects of that blade, chisel, knife or whatever, and they all mean something. Sorry for the long post. Live long and prosper!

    How many steels can really benefit, anyway? If your chisel is white #1, or a fancy sintered super steel, OK, I might entertain it, at least. I've got a couple kitchen knives that really do benefit from fine stones, and suffer from stopping at 1-2K. But, most tools are made with softer, durability-focused western tool steel, and just don't have the fine even carbides that would make it worth it. I also don't see a potential advantage, except maybe for certain types of planes - *maybe*. Just strop to smooth it out, and get rid of any microscopic rough parts. If you compared edges after some light use, to have removed any poorly secured bits of the edge, under an electronic microscope, it wouldn't surprise me if a lot of chisels and irons end up equally sharp around 600 grit as 1200 grit, much less super extra fine grits (keep in mind that sharpening on X grit will generally result in a finer edge than the grit size, too).

I have gotten used to the diamond plates and I feel like they save me time because they cut so much faster compared to the same grits. But I have also switched to unicorn sharpening method on a buffer and so now the stone part is less crucial and I find that I am less particular about the stone part of the equation.

    Diamond plates ALL require a break-in period. That explains why your stone made that change. The recommendation is to “break in” every diamond stone with a piece of steel that you don’t care about (an old plane blade, or a cheap knife), rubbing it lightly over the entire surface of your new diamond plate. This knocks of any errant, large pieces of diamond, leaving a smooth field of same-sized diamond. You’re not really losing sharpening effectiveness, though it may seem that way; you’re just preparing the plate. Hope that helps!
