S SATCDiamond Sharpening Stone 2 Side Grit 400/1000 Diamond Plate Honing Stone 8-inch Hone Sharpener White

I’m sure the similar product selling for $248 is probably better in some way, though that $ buys a lot of these excellent plates. 150/600 is sweet for flattening everything I own (which is approximately one of everything), minimal wear in after several flattenings, most importantly its dead flat to the degree I’m able to measure. 10/10, buying another just because. Oh, I did hog off some metal on a chisel setting a new bevel and it did its job beautifully. It’s unbelievably coarse and I’m here for it. Note: I have no idea how accurate the “grit” claims are and don’t care.

I bought the company's holder for this also. I'm new at hand sharpeningand saw this recommended on Youtube. It works great with a little practice.A knife with good steel will develop a razor sharp edge. Of course, you needa leather strop to seal and retain that edge. That's another story! I can shavemy arm, cut cardboard, then shave again. Only took me a lifetime to figureit all out.I use the #400 grit and it appears it will last a good long time.

4 stars due to probably grit contamination? The 1200 is still fairly aggressive and will leave deep scratches. First of all, most all the bad reviews are from people who don't know what they are doing or talking about. I'm sure there are some duds that slip through QC, but most are just ignorant. I bought the 400/1000 and 600/1200. I've only used them to grind the factory scratches off a couple Scandi ground knives. Much more grinding than is required to sharpen. These stones work very well. I didn't feel like they required much break in compared to other cheap diamond sharpeners I've used. In practicality, I don't think you really need both the stones I bought as even the 1200 is fairly aggressive. Could be due to grit contamination? Anyways, one of these and a good strop will get most any knife scary sharp. It's technique over gear.

I picked up this S SATC diamond sharpening stone specifically for guitar fret leveling, and it works like a charm. The 400 grit side quickly handles high spots, while the 1000 grit side smooths things out without needing much follow-up polishing. It’s flat, consistent, and makes the whole process faster and easier. If you’re doing fret work, this is a solid, affordable tool that gets the job done right.

I wanted an inexpensive diamond stone to sharpen my kitchen knives. In the past I've either used a variety of honing stones and a buffing wheel (slow and messy but produces an edge you can shave with), or one of those inexpensive sharpeners where you drag the blade through (fast but inconsistent results and doesn't always leave a good edge). I decided that something in between would be a better choice.I bought this based on a recommendation from the Outdoor55 YouTube channel. He uses this stone to sharpen several different blades very quickly, though he usually follows it up with a leather strop (I usually don't bother). When I saw it for sale for less than $20, I decided to try it.I used it to sharpen one of my large kitchen knives, an older Cutco that has seen a lot of use and abuse. Other reviewers state that the stone is initially quite aggressive and they are right. I placed a few drops of water on the 400 grit side and used it to (mostly) reprofile the edge of the blade. I then flipped the stone over and sharpened it with the 1000 grit side, again using some water. The stone leaves a fairly rough edge even when using the 1000 grit side, but this should improve once it breaks in a bit more.I spent perhaps 2 minutes on this blade. I didn't strop it afterward to get it really sharp, I didn't break in the stone, and I certainly didn't get anything perfect. All I did was to undo some of the irregularities that the drag-through sharpener had left behind and gave it a clean edge. When I was done, the knife was sharp enough to slice onions cleanly. It's sharp enough to use as-is, though it could easily be made sharper with a finer stone and/or a leather strop.The stone has some weight to it so it won't shift around while you're trying to sharpen your knife. No idea how it will break in over time, though I'm satisfied with its performance right out of the box. All I wanted was an inexpensive coarse/fine diamond stone that will make kitchen knives reasonably sharp quickly, and this stone does that. Someday I may strop one of the blades after using this stone to see how sharp I can get it, but for now I don't feel the need.

This diamond sharpening block works fantastic

Decent for the price. We will see how long it lasts but I have got good use out of it.

This was the missing piece all along. Been using diamond steels for a while, this was the missing piece to finally start getting thin-tomato level sharpness.
