4 Pieces Diamond Sharpening Stone Grit Diamond Plate Honing Stone for Kitchen Sharpening Dull, Blunt or Tired Edges, 5.9 x 2.48 Inches(400/600/1000/1200 Grit)

For a cheap diamond stone, these work well.You can spend a bit more and get better stones, but these are fine and will last you a year or two if youre using these in a woodshop.

I found these of good to high quality. Easy to use and a good size for almost everything.The 400, 600, 1000 grit work perfectly. Strangely, the 1200 grit acts rougher when it should be the smoothest. I don't know if it is mislabeled, a defect, or just have high spots. if it doesn't flatten out I will rub a sharpening stone over it lightly, then I'll know.

They work well. The review form asked about "accuracy". I couldn't tell you how accurately flat these are, or if the grit is on spec. But they're handy and do the job. Some reviewers mention that these stones wear out fast. To those people I say "you're pressing way too hard, let the tool do the work". I'm sure mine will wear out eventually, but I've been using them for some time now with no deterioration. I'd say they're worth the price, and if you're particular about sharpness of your tools you will achieve it with this set.

Easy to use when you need to sharpen anything with an edge! Great to have in my tool shop when I need to touch something up

I bought two packs of these on the recommendation of a friend. I usually mount the diamond plates to a board that I can put in my bench vise while I am touching up edges or sharpening. The nickel diamond plating seems pretty good. My only beef with these is that the metal backing plate is fairly thin, which means flex, which in turn means that the "flatness" that you are working on can be hard or impossible to achieve. They are light weight, which in turn might make them good for portability if you need that. For the price they are nice to keep around, hopefully I find something useful to do with them. Might try gluing them down, maybe that will fix my issues. I not saying there is anything wrong with them, but out of the package they are not flat which might not matter for some things.

These diamond plates shipped and arrived quickly, no issues. The plates are thin so a sturdy flat surface is a must to rest these plates on when sharpening. Because they are thin, it's nearly impossible to butt the plate against something thinner to prevent from slipping forward when sharpening. But at this price, it is as expected. Hope this helps.

These are cheap. i don't know much about sharpening or diamond stones but these where cheap and i needed something that would allow me to get started rehabbing some tools i had. they are thin but work fine for what i wanted them for and that was to get me going. i may buy better quality stones later when i know more but for the price I say they are working like a charm for a beginner like me. if you are too well you make that choice but i give them 5 stars for what they are.

I've started woodworking with traditional tools and have needed to do tons of sharpening chisels and plane irons. These plates have been at the center of my sharpening and I've spent days honing the blades. These plates have been reliable, give a fantastic edge, and have kept their honing ability. The cost is low and it's been a fantastic addition to my shop! I highly recommend these plates!
