Review: Good, even excellent - This is a good, even excellent, whetstone. For, it does the job, gives reasonable feedback (i.e. one can feel what one is doing), does not have any problem with slurry, and it does not seem to wear especially fast. I have used it with success on low-carbon knives and medium-carbon knives. I have not tested it on any very high carbon knife, though I imagine that it would work on such a knife. Other reviews here say that it does. The price is pretty good. I add the following (and in so doing I echo somewhat one of the other reviews). This remark of mine will concern medium or high-carbon knives, i.e. hard knives. If one is changing the angle of such a knife, and/or perhaps is the knife is really blunt, then one needs a coarse stone, like this one. For, under those conditions, using a less coarse stone makes it hard to get the knife sharp. (Still, what counts as less coarse? Perhaps 400 grit and above. Certainly 800 grit and above. But I'm talking about standard synthetic stones here. Matters might be different with diamond stones. As to natural stones, some of them are very hard, but at least most such stones will have a grit north of two thousand, which, for the sort of work at issue, will take forever.) I would not try to use the whetstone atop its box - as shown in one of the photographs provided by the seller. I imagine that that would work badly. One needs a proper whetstone holder. For _storing_ the stone, the box is fine, though I prefer the Naniwa boxes. (Incidentally: to my knowledge, Naniwa does not do a stone in the 300-400 grit range, at least not within its more serious lines of stones.)
Review: Recommend - Great stone!!!

## Questions & Answers

**Q: If I have a 20000 shapton for straight edge, would this make a noticeable difference?**
A: I had a friend who had this very same shapton 30,000 grit stone and I liked very much as you can use this for not only extremely minor sharpening for edge refinement, but also for stropping your blade regardless if you're sharpening knives or straight razors. Then I ordered mine from Amazon and unfortunately the stone I ordered never came, and to be honest, I have some Japanese Natural stones and some American Arkansas stones like Arkansas Black and Translucent can do the same job except they're not going to polish a blade as good as the shapton 30,000 grit which gives a blade an almost true mirror finish.

**Q: Why is the 30000 grit so much more expensive than all of the others?**
A: With synthetic stones, the finer the grit, the more expensive because 1) there is more material per volume and 2) they may take a little more "work" to produce. Since I do not know that manufacturing process #2 is a well educated guess. #1 is a fact. Hope this helps.

**Q: Can these be used to sharpen katanas? If so, which grit is recommended? I know nothing about stones and sharpening blades. Thank u for ur time&help.**
A: These could be used to sharpen katanas, but if you've never used wet stones before, you'll wanna practice on something like a knife to get started.  Additionally, you'll likely need multiple stones depending on the condition of your blade and how sharp you want it to be.  I use 7 stones just to sharpen one of my wooden chisels.  I start with an 80 grit to remove major defects and work up to about 10000 grit.  At the very end I finish sharpening with a jewelers rouge, which ultimately leaves the blade very sharp with a mirror polish.  If you wanna see more detail, check Paul Sellers "How to sharpen a chisel" on YouTube.  That should get you better tuned for what you're trying to accomplish.  Cheers!

**Q: What lapping plate should i use to flatten the waterstones purple #30000?**
A: I just use an EZE-lap lapping plate. A broken in DMT 328 or just about any other diamond plate would work.

Great stone!!!

### ⭐⭐⭐⭐⭐ Worth the extra money for this quality whetstone...
*by J***D on 10 July 2020*

I have a few whetstones, ranging in grit from 250 to 8,000 and I have been previously using my 8,000 grit stone to finish off my Global Knives - none of them in the price range of Shapton, to be fair. I've become reasonable adept at sharpening them freehand and they were pretty sharp, I wouldn't say razor sharp but very sharp nevertheless. This Shapton stone, at 12,000 grit, is a different level. I used a 3,000 then an 8,000 grit stone to get a really nice sharp edge and then went to work with my new Shapton 12,000. The stone I ordered came directly from Japan and the instructions were in Japanese. However, I did a bit of research and it was recommended that you soak the stone in water for about 5 or 6 minuted prior to first use. On further uses, it's not recommended to soak the stone as it can soften the stone. For future uses, the stone should be sprayed with water on the surface prior to use. Following use, once clean of any residual dirt, it should be allowed to dry prior to being placed back in the box. The finish you get using this stone is at another level to the stones I've used before. I found the blade edge was genuinely polished and is was unbelievably sharp. This stone is quite a bit more expensive than stones I've used before but I can see why. It is far superior in quality. I would highly recommend this stone for anyone who is serious about sharpening their knives. Genuine top quality product.
