Review: An excellent medium-fine water stone, this and one or two strops are all you need for a good edge. - As others have observed, the grading of 1000 is probably a little high, it might be more like 800, it's definitely a medium stone rather than a fine one. Whilst you can use it to reprofile an edge, it will take a while, this stone excels at repairing and maintaing an already profiled knife. It's a very high quality stone, its consitency is uniform, there are no grit lumps (giving rise to pimples) and the wear in consistent over the whole surface. It is of one grade throughout, both sides cut the same. It's easy to use, do fully read the enclosed instructions though since some online videos are incorrect, it's not just a "splash and go" stone, it's porous throughout and requires an initial soaking period especially if it has been left to dry out. You also need to regularly splash as you sharpen to both lubricate and remove slurry. It's not as convenient as a dry diamond stone but it's a fraction of the price. In practice using it with a small towel around it is fine, once it has been soaked you only need a teaspoon of water every so often to keep the surface lubricated and clean. The case is nicely designed as well, it is sturdy and clicks closed positively so that even if you do the unspeakable and drop the stone in the closed box it should still be protected from fracture. There are four non-slip rubber button feet on the underside and a four-sided fence on the lid which retains the stone perfectly whilst allowing water and slurry to drain from the gaps in each corner. This means you don't need to buy or make a custom stone holder, the case does a perfectly adequate job for most people. The whetstone has a very nice smooth grind feel when sharpening, you can easily gauge from the drag how much metal you are removing, the tactile feedback from the stone is excellent. Unlike diamond stones this stone will wear and depending on your usage and technique/proficiency you will need to periodically flatten it which requires investing in a separate flattening stone, but it's well worth it and if you use and maintain this whetstone properly it will give you many years of faultless service and hundreds of sharp knives. Whilst you can buy a finer grade stone to finish on, you don't have to. The orange Kuromaku is a good enough compromise that you can use it to both shapen and finish needing only one or two leather strops with diamond paste to raise a knife to a razor edge (dependent on the knife of course). Overall this is an excellent quality stone, I'm very pleased with it and I also believe that it represents excellent value for money since you can just about get away with just the one expensive whetstone plus one flattening stone and a few rawhide strops. (You can do major reprofiling using those cheap diamond stones first.) As a novice I watched many online tutorials before purchase and I went with the consensus of opinion that this was an excellent value one-stone sharpening solution and after using it successfully (I sharpen all my friend's knives for practice) I concur with them all. If I buy an additional whetstone it will be probably be another Shapton.
Review: Worth the extra money for this quality whetstone... - 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.

## 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.
