10Pcs Diamond Knife Sharpening Stones Set, #80#200#400#500#600#800#1000#1500#2000#3000 Grit, Diamond Whetstones with a Non-Slip Base for Ruixin Sharpener, Knife Sharpener for Kitchen Outdoor

I’ve been using this 10-piece diamond knife sharpening stone set with aluminum blanks (80 grit to 3000 grit), and overall it is a solid value for the money. The full range of grits covers basic to fine sharpening needs, but for me, the standout stones are the 400, 500, 600, and 800 grit plates, which I consider the most practical and frequently used for daily knife maintenance. The stones are consistent in grit and durable, and the aluminum backing provides a stable, flat surface for sharpening. While not premium-grade, this set performs reliably for hobbyists and home cooks who want a versatile sharpening solution without investing in multiple individual stones. Overall, this set is practical, dependable, and especially valuable for its mid-range grits, which I find essential for maintaining sharp, precise edges.

Very versatile and easy to manipulate/use with multiple (10) different grit levels. I have been using the #100, #200, #400, #500 and #600 grit to reshape some of my TOPs knives 1095 steel blades and they cut through that steel extremely well. I have reshaped and honed the blades on two of those knives already and I have noticed that there is almost no wear at all on the grit surfaces, which makes it obvious that I will be able to get a lot of use out of them.

This is basically a good product, but at first I was frustrated with them. I tried using them dry and had trouble getting a good edge. Then I used water and did little better - except they started to show flash rust. I presume the plates were rusting because I was sharpening stainless blades. So, I was not too happy when I tried them with mineral oil. They worked great. Good product as long as you use mineral oil with them.

The regular stones that come with the Riuxin sharpening kit are OK for finishing edges but for removing nicks or sharpening really hard alloys (like D2), something more aggressive is needed. These diamond laps work well on the metals which prove difficult to work with natural or aluminum oxide types of abrasives. I learned long ago not to bear down too hard with diamond laps. Doing so tends to tear the diamonds out of the lap's base metal as well as imbed the detached diamond grains into the softer materials they're being used to wear down. Just keep the lap wiped when with a little water while using it and don't press too hard. Ceramic knives are becoming more common these days. They're impossible to sharpen with anything besides a diamond lap. I use the finer diamond grits to refine the factory edges that come on ceramic knives. Ceramic blades eventually chip no matter how cautious you are about using and storing them. The coarser diamond grits are useful for removing nicks as well as resetting the ceramic blade's cutting edge angle if needed.

This is a good collection of sharpening stones, and they work well with the jig. If I could come up with a con, it would only be that the stones occasionally work loose from the clamp and misalign. Is that the stones' fault or the jig? Other than that, I am happy with the performance for the cost so far.

I’ll preface this by saying that i sharpen for a living and have done so for many years. My sharpening has included high end chef’s knives, medical equipment and much more. For knives I use, what i consider to be, the best knife sharpening system on the market. Before I was willing to charge for sharpening knives I researched sharpening methods and tools for 20 years so I do know something about what’s out there. Just out of curiosity, and that’s one of the reasons I began sharpening 60 years ago, I bought these stones with the understanding that they would fit my own sharpening system. They do. Here’s the scoop on these “stones:” 1. They are priced so low that you might think they’re is something wrong with them…read on. 2. They arrived quickly as promised 3. There are many more grits than you really need to do good work 4. The grits are not related to any other grits that you might be accustomed to and may, indeed, be random numbers chosen to be somewhat close to known grits. 5. These “stones” are great for practicing your sharpening but not great for any long haul serious sharpening. They will sharpen, yes, and they are great to use for knives that may be terribly injured so that you don't have to use your good stones to do this. Again, if you want to do a lot of practicing, and you should, before you use your good stones…these are ideal and I’ll have my students use these in a heartbeat with the understanding that high quality sharpening does require high quality stones and equipment. There’s no free ride here. Given this information, yes, these “stones” have a place in your shop but do consider them disposable.

Yes there are better quality stones out there. But honestly these work fine. I sharpen about 5 knives a week for friends, family and co-workers. One set lasts me 6 months. That's really good. Same results better price. I do polish my blades with gunny juice on my strop. People who insist you need better are just trying to justify the money they spent.

These are good for getting started with a pushrod style sharpening system. They’re pretty thin and if you use a lubricant like wd40 then they will come off the plastic. I was able to glue them back on tho. They will wear out after a while, which is not necessarily a bad thing because the 3000 grit plate will just give you a better and better polish as it gets smoother. It’s very straightforward/easy to get a scary sharp edge on a knife with these, assuming you’re using them in a pushrod sharpener.

Ruixin pro RX009に装着して研ぐために購入。 マグナカットも含め、ちゃんと研げました。 #3000では反射で映るほどの輝きが出るほどは研げないので、別途砥石で研ぎあげることにしました。 良い買い物でした。

Outstanding value. Probably not the most long-lasting grit, and the higher range grits (1500, 2000, 3000) seem very similar, but I got heaps of use out of these and the price is unbeatable.

They work great!

全体的に品質が安定してない。 1500番以降の番手の粒度がほぼ一緒。

seems ok have not used enough to know
