Excellent Diamond Sharpening Stone. Great for expensive knives
I’ve tried traditional whetstones in the past and never had great results, so I was hesitant to experiment again, especially since I own expensive knives and didn’t want to risk damaging them. I also avoided cheaper sharpening tools for the same reason. This diamond sharpening stone worked extremely well. It sharpened my knives quickly and evenly, and I was able to get a very sharp edge without any damage to the blade. The surface feels consistent and effective, and it performs much better than the whetstones I’ve used before. It’s easy to use with a little practice, even if you’re not a professional. Overall, this is a solid option if you want reliable results and care about protecting higher-quality knives. Pros: Sharpens quickly and evenly Safe for expensive, high-quality knives More effective than traditional whetstones Durable surface Cons: Requires some learning Does not come with a base to keep it in place

Outstanding Diamond Bench Stone for Performance, Longevity, and Learning
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.

Decent, but I would spend more and get something nicer
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.

Heavy, solid, and pretty flat; way better than I expected for the price.
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.

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.

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.

Good for fast stock removal on 400 grt and fine finish on the 1000grt. Price is good compared to other quality stones. If you're into sharpening often,on a budget, go for this. Best bang for your buck.
