S SATC Diamond Sharpening Stone 2 Side Grit 400/1200 Diamond Plate Honing Stone 8-inch Hone Sharpener White

I’m a huge fan of S SATC diamond bench stones, and this 400/1000 grit double-sided plate continues to deliver excellent value and performance. Like most budget-friendly diamond stones, there is a small amount of lower-grit contamination out of the box, but it’s not excessive and becomes far less noticeable after a short break-in period. Once broken in, these stones settle down nicely and perform very close to their rated grit for consistent, predictable sharpening. What really stands out is durability. My original S SATC stones are approaching two years of regular use, with close to 300 knives sharpened so far, and they still have plenty of life left. The cutting speed remains strong, which is exactly why I always recommend diamond stones like these to new sharpeners. Diamonds cut fast and provide immediate feedback, making it much easier to learn how to hold a consistent angle, raise a burr, apex the edge, refine it properly, and then finish with stropping. Compared to water stones or natural stones—which cut much slower and offer delayed feedback—diamond plates dramatically shorten the learning curve. That faster feedback helps beginners understand what’s happening at the edge in real time instead of guessing. Inexpensive, effective, and long-lasting, this stone is an easy recommendation for beginners and experienced sharpeners alike.

This is for the 150/600 plate; I got it to flatten the backs of some plane irons and chisels. I fully expected this to be a couple of thin plates stuck with spray adhesive to a piece of 3/8" aluminum plate or something similar, and hey, that was going to be totally fine. It's $23. Instead, it appears to be a solid chunk of 8" x 2.75" x 3/8" steel, machined as flat as I need it to be (again, it's $23 so I am not expecting to use this as a machinists' reference; there is a very slight hollow on the 600 side of mine.) with the cutting material embedded directly in the surface of the steel. It is heavy. In my very brief testing, both sides cut plenty fast. A chisel sharpened up to 600 is honestly pretty sharp. Yes, it's fun and useful to make mirror finishes on cutters. You can make lovely shavings at 600. Are there better sharpening systems out there? Absolutely! But if you are reading the reviews on this, I bet that either you don't need a better quality sharpener right now, or that you have something better and are thinking of this as a "I don't want to risk getting something gross nasty on my good stones" option. It's good in either case. Will it last forever? I don't know. I don't care. It is $23. For reference, a similar setup from Eze-Lap would run about $185. This thing also came with little silicone rubber end caps that provide some grip if you don't want to mount it in a sharpening board. (Or if you're moving it, I suppose they'd protect it if you drop it.) Realistically, this is probably flatter and more durable than virtually anything you could get a hundred years ago, and craftspeople then made their tools wicked sharp and crafted awesome things with them. If you're on the fence, get this plate and practice sharpening. If you hate it, you spent $23.

This is a good product for the price but I would spend a little more and get something nicer. The coarse grind is fine but fine grind side is not. This will work for basic sharpening, but if you want to get something razor sharp you're going to need to spend a little more money.

AN IDEAL BEGINNER'S STONE - Amazon carrys hundreds of brand-variants on the 35¢ double sided cheap silicate soaking stones. Some sellers charge $18 some $48. These are poor. Very hard to learn on. If you want to learn to sharpen knives, BUY A DOUBLE SIDED DIAMOND STONE like this instead. Sharpening on this stone (or the more expensive, but similar Sharpal that's well rated) is much easier when learning. This has the two indispensable grit ranges. If you can learn to 1.) hold your angle consistently. 2.) form a bevel (about the same) on both sides, and 3.) use your fingers to feel, follow the Burr you will be on your way! - Oh. Burr is important. Be sure to learn about burr. 400 grit shapes your angle & cuts the serrations all the way to the edge that successive grits refine, then hone. 1000 grit finishes. 1000 grit is the coursest fine stone or the finest coarse stone. Honing with a strop after 1000 grit sharpening is an acceptable substitute for laboring up through the grits. (I say this, but I often do sharpen on 2000 before honing) A whisper sharp & keen edge can be quickly made and maintained on any kitchen knife with this stone, and some stropping on leather. Finer grits bring some refinement at the expense of considerable work time. Grits above 3000 hone more than sharpening - reducing the coarseness of the corrugation - the 'Scratch Lines' cut by the low grit & middle grit passes. Above 5000 grit the stones become expensive because of complex traditional factors of Japanese blade culture. Essential for shaving with sharp straight razors. Not useful really for kitchen knives. Diamond compound (cheap or pricey) on a leather strop probably a quicker easier honing method. Save money. Enjoy this stone. Learn. Have sharp knives.

Great inexpensive stone... I didn't have a holder for it, but placed it on some friction padding similar to what I use for my woodworking projects and it worked fine. Nice to have two different grits to work with as well. I will probably buy a second one to have as a backup. Used it on an old number 5 hand plane blade and chipper and it worked extremely well. Good product and I would definitely recommend.

This diamond plate is great for what it is. It's strictly for profiling. Don't need to be anything special but it works great for profiling. I also bought the sharpal double sided plate. This works just as well as that one. I just use this one to preserve the more expensive one. I will be buying another one of these soon just to have for when this one wears out. They are cheap yet good. It is good and solid. Has a very nice weight to it. It doesn't fit in my current stone holder so I ordered a new one. I'm sure it'll work great. Most other cheap stones like this are paper thin and bend. This one is thick and flat. Just great overall. I'm not a fan of the pattern on the plate but it doesn't effect the way it works. Either way I will buy Another and I suggest you do to.

None of these last forever. They cut aggressively at first, then at a lesser rate over time until you decide to replace them. I used to use Trend diamond plates until Trend transferred manufacture to China and changed the core material from machined steel to some synthetic. That’s when I tried this one because there was little to lose for $16.00 on sale. The plate is steel and super-flatness isn’t required for ordinary woodworking tool sharpening. I like my Sharpal plate better, but it costs four times as much, and given my attitude that these aren’t a lifetime investment, the price is right and they seem to work as well, so I have no complaints. When a $100 Trend plate wears out, that’s a bigger problem than when a $16-20 plate wears out. I didn’t detect grit contamination between the two sides. If this wears out more quickly than the expensive plates, I’ll just replace it with a fresh one and won’t cry much about it. It wouldn’t surprise me if these aren’t nearly as flat as more expensive plates. A machinist might notice a difference, but a woodworker or knife sharpener probably would not. Buy the ticket, take the ride. The plate comes with two rubber ends that keep it from moving around during use, and so it won’t scratch a counter or whatever surface it’s used on.

As someone who has always been meticulous about maintaining the quality of my knives, I was pleasantly taken aback by the SATC Diamond Sharpening Stone's superior performance. The first feature to catch my attention was the generous size of the stone. Clocking in at a full 8 inches, this sharpening stone means serious business. Its size not only facilitates efficient sharpening of larger blades, but also enhances the overall handling and usage experience. This is especially significant for those with a larger set of knives or those who frequently need to sharpen their tools. A significant aspect that sets this stone apart is its weight. There's a certain satisfaction in handling a tool that feels solid and robust, a mark of quality that's not seen in many other sharpening stones in the market. SATC has struck a perfect balance, giving this sharpening stone just the right amount of heft - a reassuring presence in your hand, but not cumbersome or unwieldy. When it comes to performance, the SATC Diamond Sharpening Stone truly shines. The difference it made to my knives was palpable. Each stroke brought my blades back to life, sharpening them to a razor's edge, ready to perform at their peak. Moreover, I'd like to highlight the consistency of the sharpening. There were no hotspots, no uneven areas - just a uniform, diamond-encrusted surface that worked wonders on every inch of my blades. As a result, my knives now cut effortlessly, giving me precision and control like never before
