The 800 grit Chosera Pro fills a specific gap that experienced sharpeners eventually discover: there is real distance between a 400 or 500 grit stone and a 1000, and bridging it in one step costs time and effort. The Chosera 800 sits cleanly between those two zones - aggressive enough to set bevels quickly and handle edges that need more than a quick touchup, refined enough to leave a scratch pattern that transitions smoothly to a 1000 or 2000 without laboring through extra steps. One experienced reviewer made a useful technical point worth knowing: a Shapton 1000 grit stone is technically rated at 800 grit under the current JIS system, which means the Chosera 800 performs in the same range as many stones sold as 1000 grit - just with the Chosera line’s characteristic speed and feedback. Please note that Naniwa has updated the name of this stone from Chosera 800 to Naniwa Chosera Pro 800. The stone itself is the same trusted formulation.
The Chosera Pro line is known for three things: fast cutting, slow dishing, and a scratch pattern that polishes above its grit rating. The 800 delivers all three. The resin-bonded construction is designed as a true splash-and-go stone - soaking is not recommended and not needed. Splash the surface, start sharpening. One reviewer who compared it favorably against more expensive and more publicized stones said the feel and results exceeded his expectations, and paired with the Chosera 3000 described the combination as outstanding. Another called it a 1000 grit stone on steroids - faster at the same job, with the same smooth, consistent Chosera feel throughout.
What Customers Are Saying: All six reviewers gave five stars. One experienced sharpener called it his favorite medium stone, noting the feedback when raising a burr is the nicest of any waterstone in its class. A second compared it to the Sigma Power 1000 and found it faster and equally smooth, noting it works well enough that he can jump from the 800 directly to an 8000 grit stone on small or hollow ground edges. A professional chef who uses it as part of a progressive series called the combination of 800, 2000, and a strop the best edges he has achieved. The consensus is a stone that consistently outperforms expectations at its grit level and earns a permanent place in serious sharpening kits.
Care Instructions: Splash with water before use - do not soak. Flatten regularly with a diamond plate to maintain a true surface. Store dry between sessions. The 20mm thickness gives this stone excellent longevity with regular flattening maintenance.

y vary, in most cases, I believe you could go to the same stones from this that you would go to from a 1k. On edges that are either small, hollow ground, or micro beveled, I've been jumping from it all the way up to my Snow White 8k. This may not work for you knife and razor guys, but many of us woodworkers love being able to do these big jumps. On larger areas of steel, such as blade backs, I put my Sigma Power 6k into the mix, and while it does take out the 800 scratches without any trouble, I'm thinking a Chosera 3k, which I've used but do not own, would be an ideal stone to follow the 800. I was expecting this stone to be quite thirsty, and while it works best with a soak, it works quite well with a heavy splash; the water tends to sit on top for a while rather than being sucked into the stone right away. Also, because it is relatively hard and fast it really helps you to get your edge geometry correct at the get go. So far I'm also finding this stone less prone to overloading and clogging than some of the other Chosera's I've used, and I think I like it a little better than the Chosera 1k, which I don't own, but have used a number of times and quite like also. This stone doesn't get a lot of press, presumably because it is an 800 where as 1k's tend to be more popular, but keep in mind that a Shapton 1k is also technically an 800 grit stone under the current JIS rating system. If you are looking for a ?medium? grit foundational stone, the Chosera 800 is a serious force to reckoned with. I highly recommend it!

I purchased this stone to use as a more aggressive alternative to my Sigma Power 1k. I'm finding it to be a great foundation stone for resharpening edges that need a bit more than just a quick touchup. I would categorize it as a 1k on steroids, as it does the same job just faster. It also has that same lovely, consistent, and smooth feel of the whole Chosera line. It's quite fast, especially when freshly lapped, and while it does leave slightly coarser scratches then a 1k, it is still fine enough that I can use it in the same progression in which I was using my Sigma 1k.
