Diamond Sharpening Stone 2 Side Grit 150/600 Diamond Plate Honing Stone 8-inch Hone Sharpener

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 is a good stone and typical of Japanese product quality. Quickly puts a sharp edge on your knife and recommend to anybody looking to purchase their first stone.

Thanks to both Amazon and the seller. It is awesome 👍😎 I think I will take up tool sharpening as a hobby now.

The 400 is just perfect for butcher or kitchen knife , work fast and give a regular toothie edge

Praticidade e eficiência.

Works well a great replacement for my old stone that could barely remove material. 400 is good for removing chips and bringing back an edge, probably a bit aggressive for ordinary use but it is good quality and is showing no signs of wear.
