This Kohetsu 2K sharpening stone is an exclusive item for Chefknivestogo. The stones are ceramic based, require a short soak and will cut a wide variety of steels including HAP40 and Aogami Super that you find in the Kohetsu line of knives. They are formed and dried naturally in the air without any heating, and this gives them a uniform and quick cutting sharpening experience. Professionals particularly among the people working in the market places like Tsukiji in Tokyo use this stone. This 2K grit stone is 205mm x 70mm x 30mm so it's a large stone and should last a long time.
Product Reviews
Excellent stone; outstanding value., January 22, 2020Posted By: Richard
A short soak (1-2 minutes), and the stone is ready for business. It handles my 60-64 HRC knives easily. Thicker than my other stones and slightly narrower; the added height is welcome, and the width isn't missed.
Oh yeah -- it feels really good. Cuts with ease -- swarf generates quickly. And leaves a mirror edge with a hint of tooth.
CKTG shippedb it well-packaged and quickly.
Did I mention that I'm very pleased?

Finally, the right stone, October 28, 2019Posted By: Christopher Sherwood - verified customer
I have a rough, low-grit stone to rest an edge. Then I had a fine grit that turned out to be more of a polisher. But I didn't really get a razor sharp edge until I got this one @2000 grit. It also cuts fast as previous reviews protest. I'm now getting sharp knives and couldn't be happier.

Very good 2k for stubborn steels, October 27, 2019Posted By: Ryan R
I've messed with this stone for a few months and I have to say I like it quite a bit. It is kind of a medium hardness stone, it will release abrasive somewhat easily and is possible to gouge but it's not super soft to the point it's annoying. I find it to be a somewhat good compromise in the hardness department and I think it needs to be like this in order to work like it does with very wear resistant and hard steels. It has a very nice feel and feedback and at 30mm thick it should last a while. It needs a decent soak and doesn't dry very quickly. The real strong point of this stone is its ability to cut high wear resistant steels just as the description states. I recently touched up a Manix 2 in CPM-M4 on this stone and it had absolutely no problem cutting that steel, anyone who has sharpened M4 will know that's not a small feat. I took the same knife to a Shapton Pro 5k afterwards and could immediately tell that it wasn't cutting this steel nearly as well, had a very strange feel and feedback of the knife basically skating across the stone. So if it can easily cut CPM-M4 it shouldn't have much problem with any of the other "super steels" out there. As far as the edge produced by the stone it obviously differs from steel to steel and knife to knife. For the most part it will produce an aggressive edge for 2k on your typical steels because it cuts so aggressively into them. Once you get into harder steels it produces less tooth and more polish as you would expect. Overall good stone that I will mostly use after diamond plates for really stubborn steels.

I sharpen woodworking chisels and plane blades. Used 1k and 4k Nortons and 6k Arashiyama . Could never get a good polished edge.Allways had scratches . Also have 8k kitayama stone that I do not use much. I talked to Mark he said the 2k Kohetsu would be good stone for me to use with my tools .What a improvement this has made in sharpening .I also picked up the 800 Kohetsu. So after sharpening 2 chisels and 2 plane blades . All the years of using the Nortons the 4k was the problem . Now it is 800 -2k -6k to a nice scratch free polish .Now I can see a little more mirror finish when I use the 8k . Both Kohetsu stones cut very fast .I guess it comes down to quality . Thank you Mark

Following the advice of several senior CKTG stones fanatics I bought the 800 / 2K set for my Takeda NAS. Love the speed and tooth the provide for everything from an old cuisinart santoku to Miyabi SG2, Kikuichi Carbon, Kikuichi Swedish, Koishi, and my beloved Takeda. A long soak required but the feel and size is great. Highly recommend!

I just have to say this, if you can only afford one stone right now I would highly recommend this Kohetsu or the Green Brick. A 2000 grit is a very nice grit for refining or finishing if you don't need a highly polished scalpel edge. I have a nice 5000 grit King that I seldom use anymore as I only notice a polish not necessarily any sharper. My knives are plenty sharp after a 2k finish...lots of cuts have been proof to that!

Short story...If you find these stones in stock, buy it! It is amazing. I was lucky to get this one as one of the last in stock along with a knife ( Yamashin White 105mm Tall Petty) that is known to be not so sharp ootb. Within a few licks on the Kohetsu 2000, it was shaving hair of my arm with ease. The stone muds very quickly and has a brilliant feel and feedback. I soaked it for 30 minutes in a stone pond and put it to work and work it did, the knife went from 3 of 10 to 9 of 10 in minutes and I never touched it to a higher stone. My new favorite just arrived today.

I'm new to sharpening with water stones, so this is based on limited experience. I wanted an intermediate stone to transition between 1000 and 6000 grit. This worked perfectly for that purpose. It cuts fast, and has excellent feedback. It's not super hard or soft, but it is possible to gouge it if you get careless. I was surprised at how well it polishes. It could easily be used as a finish stone if a more toothy edge is desired. Very happy with this stone.

This an awesome stone for 2 main reasons. 1, If you need to build a new edge, it's an easy transition from 1K and you refine a sharper edge. 2, if already have an edge and you just want to resharpen. This is a good base to start and move up to finer stone. Thank you!

Can't make too many claims yet since i've only sharpened one knife with it so far, but it seems to leave the ideal edge I was looking for for my western stainless knives and the knives i sharpen for my co-workers and friends. I was using a "3000" grit side of a 3000/8000 taidea combo for this purpose before, but wanted to find a larger, harder stone for the job, since the taidea is soft and ill cut into it every once in a while, Bought the Naniwa Green Brick, but found it much too fine an edge (i'd guess around 3000-4000 depending on how you sharpen) for western knives. then tried the shapton glass 3000, but it was also too fine a finish, being finer than the green brick, even. This one is the closest to the taidea's finish i have found yet, but maybe a tad bit finer, which is fine, because my wusthofs will still keep the edge this stone produces. Nice and toothy for a great all purpose edge that will cut through proteins and tomatoes alike. overall, the stone feels pretty hard, and it will actually feel rougher than it actually is until you sharpen your first knife with it, smoothing out to its final smoothness in the process. Its a permasoak stone, which is perfect for me. leaves some mud, but not crazy like a soft king or my taidea. less mud than the naniwa. it seems like a high quality stone from what i can tell so far and seems to be worth the price considering it will probably last a good while before i'd need to buy a new one. if you sharpen a lot of western knives or use them, i think this is the ideal finishing stone.

This is almost a copy of my 800 grit stone review. I have been using these stones for about ten months and they are very special. I sharpen almost every day and use the Kohetsu stones in almost every situation. The 2K is a muddy stone that has great feedback and cuts fast. Surprisingly, it does not wear quickly. It works well with kasumi finishes, with the hard high-carbon steels, and with a variety of hard and soft stainless steels. I use, or have used, many of the high-quality sharpening stones. The Kohetsu 2K stone, in particular, produces a unique, very sharp aggressive edge. The finish is dull, but edge quality is excellent. The Kohetsu stones have their own personality and feel. I think you can appreciate their distinctiveness if you have already spent time sharpening with other high-end synthetic sharpening stones like Choseras, Shaptons, etc. If I could buy a full set of these, I would.
