Gotta say i didnt expect much from these, i was very pleasantly shocked....If you are trying to get a mirror polished edge on custom knives these are not for you, but if you are wanting a set to maintain your edc knives, shop tools, etc. These are fantastic for the money, ive had them for months and sharpened a few knives I've made and all the knives in my house with them (mostly just to test em), chisels, spiral drill bits, and so on...no they probably aren't gonna last you the rest of your life, but if you're just learning, they are great beaters to do just that, buy yourself these stones a sharpal angle guide and youre ready to go...my only complaint is in the durability area, they are thin and will bend if probably if you throw them In a drawer with a bunch of junk, so I'd either mount them to a board or find a small box, I keep this set in a small knife box that was about the right size, in my pickup to have with me...anyway great value for the price, im very happy with them

These were highly recommended by Rex Krueger as the most affordable sharpening option for beginner woodworkers even beating out the scary sharp 3m micro sharpening films & sand papers. I’ve been very happy with their performance on hand plane irons, chisels, and some kitchen knives with oil or water. They seem to keep a consistent grit and don’t wear unevenly right away like some really cheap diamond stones that I’ve used before. They are thinner and narrower than I would like, but for less than a quarter of the price of high end diamond or lapping plates, I am very happy with them.

Haven't had the chance to try them out yet. Noticed some minor piting at the edge of the two top fine grits however I don't think that will affect my use of them. Interested to see if like the 200 grit will help remove a ton of material to get the right profile on some chisels. I will come back after I run some chisels on these. Excellent deal at $4 and some change a piece. Compared to some other reviewers I got the correct grits. They will just have to have the seller send a replacement. For now it's a complete 5 stars from me.

For the money these are excellent, I am pleasantly pleased with these plates there is only one caveat they need to be broken in first so don't get upset and think that they are too rough because they smooth out after you use them for just a little bit so sharpen an old knife or a chisel with them to begin with.

The 200 & 400 grit plates lost almost all of their grit in the first use. They were the smoothest of all of em after 1 or 2 chisels being sharpened on em.
