10000 Grit Natural Green Oil Stone for Fine Polishing of Knives

Update 2: Reminder these are quite hard and brittle. I accidentally knocked my stack of stones over and this one broke my thinner 4k and lost a 1/4" of a corner. I received that blue Chinese 12k from chinaexpress and though I don't have much experience with razor sharpening as others I agree with others that I don't think it's a 12k. It's a soft quick lap, looks to be natural as it claims but I can't even begin to guess what it is actually made of. The comparison? I did go through the whole range again on the Chinese one and it doesn't seem to get sharper than this one. I think you could use either of the two and shave but probably better to then go to a loaded strop for both. If I was going to use one to shave without the diamond stropping compound I have I'd probably go with this one. After I was done it cut arm hairs half way from the skin fairly easily, with blue Chinese it was kinda able to. Going to .5 compound after both seem the same. I felt there was more surface scratching from this one but that could be an error in honing through the stages or it takes longer to get through the previous scratches just because of how slow and hard a stone it is. I think the blue chinese might have more feedback but being softer you might accidentally dig in and need to redo. This stone is very very hard and feels like your honing on glass, I don't feel like I'd worry about digging in if thats even the correct term. This one has a crystalline structure and the surface has very tiny gaps and fissures which is just do to being what its composed of so very light strokes so your edge doesn't hit those but rides over em. Still very happy with it although I haven't compared it to more expensive known good stones but quite honestly I'm not gonna bother investing as it doesn't seem super necessary, it shaves, strop it with compound it shaves incredibly so why bother. Obviously results may very since both seem to maybe be natural, stone to stone variation could offer a different experience. It's cheap try it out, if you don't like it well it looks nice and would imagine if thrown through someone's window, on one hand their windows broke and probably pretty miffed but on the other hand they could probably appreciate the fact it's nicer than a 99¢ brick. Update 1: I just want to stress again I'm not super experienced with stones so take what I say with a grain of salt. I have further looked into reviews of stones like these and most say they are no good for finishing on, maybe a lead up, but there are more expensive ones you could just skip this one to finish with so I don't see the point going that route. On the other hand forums and groups are pretty notorious for just adhering to tried and true methods, not just knife/razor sharpening, n close there ears and shake there head or just make up stuff for things they never tried so it's never a good idea to rely on those kinds of places 100% and just give something a shot if you can afford too. I lapped it originally the best I could with a 400 or 600 grit diamond lap, can't remember what it was. Then recently lapped it, again, the best I could using the same side with wet 2000 grit sandpaper over it and it seems my straight razor is sharper now tree topping or whatever the hairs on my arm without going to the skin. I don't have granite to lap to but might find something later on. I ordered a Chinese natural "12000" I'm gonna try and might have some reference to compare the two. I could get an actually 12k sharpton but don't feel like spending the cash on it atm. I wish I could compare it to an actual 10k stone but they are lacking on Amazon at least in the more known brand category's. Either way it shaves with or without using a diamond paste strop so I'm still happy with it. Again it looks pretty sick and I have some angle grinder stone polishing discs that I still want to polish the button and the sides with if I ever get around to it that is. Last of note is that it laps fairly quickly the initial one took a bit to get it flat but my follow up with the 2k paper took moments. These are quite hard and highly doubt you'd put any wear in just honing razors so they should keep flat. Also since it's so hard it's pretty slow and should probably do a lot of passes but again I'm pretty new to this. I did go through my same stones with my carbon steel 10" French Sabatier... nervously cause I suck at sharpening knives and actually managed to have a scary sharp shaving edge which is beyond good for cooking knives. Final note I didn't mention is to be carefully of banging it on anything. I got a small chip out of the corner at some point without me realizing it and I know it didn't come that way so I imagine dropping it could break it. Original: I use it as a finisher for my straight razor. Not sure if it is 10000 grit as I don't have much experience with higher grit stones but it seems to be higher grit than my 8000 and noticably better shave after stropping without compound to compare the two. So I'm more or less happy with it. Looks cool as well. I want to polish the bottom and sides so it will look cool on my bench where I put all the normal stones away. I like the size alot too most the others are noticably smaller and this fits in the same rubber base thing my 8000 came with and also was well packaged with both sides protected by those rubber things.

The moment you use this stone, you'll feel like you've unlocked a new level in "Knife Sharpening: The Game."

The sharpening stone is a great addition to the set I already had that needed something finer than 8000 grit. With some patience, dexterity, and repetitive mental focus, this thing makes my knives slice cleanly through the corners of paper, leaving no jagged edges, cuts meat like it butter, and can amputate limbs, so do be careful. This is a great value as this will likely last me the rest of my days.

Does a great job sharpening knives. Great finish.good value for money

Easy to use and clean. Very durable and easy to sharpen whatever you want. Makes our knives super sharp. Great value for the cost and seems like the it will last forever. Flat on top and stable inside the silicone base. Very useful!

Don’t know if it’s actually 10k grit. It is almost non abrasive like a sheet of glass. I bought this to polish a single bevel edge and it worked for that but its utility for the average sharpening job I’m dubious of. It’s pretty, actual stone, and finished well.

Stone came wrapped up nicely in a foam block with a foam lid and secured with packing tape. Silicone anti-slide base on top and bottom to protect the faces, ends, and corners. No chips on any surfaces or corners... perfect condition. The stone has very faint swirl marks on the faces (only visible upon rubbing mineral oil on it). I dragged a blade over them and couldn't feel any irregularities and after the first use they've just about gone. This stone is for final polished edges. It's for super fine honing of an already sharp edge. Very hard and takes very little metal off, but after using it does have fine metal slurry in the oil when wiping clean. I honed swivel knife blades, along with all my leather working blades, skinning knives, straight razor blades, and my chisels and plane blades... All have a super clean mirrored finish. The stone shows zero wear after all that and no discoloration as some see when using water. I use mineral oil... I'm overall very happy with this purchase. This stone will literally last a lifetime and hones edges beautifully. A wonderful addition to my sharpening/polishing arsenal. No regrets here!

Used it to sharpen my straight razor and it shaves like new.
