When the block is intended for installation on a bench it is called a bench stone. Small, portable stones (commonly made of bonded abrasive) are called pocket stones. Being smaller, they are more portable than bench stones but present difficulty in maintaining a consistent angle and pressure when drawing the stone along larger blades. However, they still can form a good edge. Frequently, fine grained pocket stones are used for honing, especially "in the field". Despite being a homophone with wet in most dialects of modern English, whetstones do not need to be lubricated with oil or water, although it is very common to do so. Lubrication aids the cutting action and carries swarf away.

Diamond plates are available in various plate sizes (from credit card to bench plate size) and grades of grit. A coarser grit is used to remove larger amounts of metal more rapidly, such as when forming an edge or restoring a damaged edge. A finer grit is used to remove the scratches of larger grits and to refine an edge. There are two-sided plates with each side coated with a different grit.[14]
The newly designed dual-sided combination whetstone from Fallkniven features a super fine white ceramic stone (0, 1 micron) with a grit of 1400 to 2000 and the dark grey ceramic stone is made of synthetic sapphires (1 micron) and has a grit of 800-1000. There is no need to add any oil or water, just lay the blade on the stone, raise the blade's spine and deburr your blade on the grey side until it has a razor-sharp edge and then use the smooth white side to get a nice polished edge.
You've acquired a good chef's knife, you're using it almost daily to make tasty dinners for the family, and it's stored in a nice knife rack or a magnet for safekeeping. So why stop there? Keeping that knife's edge fine will make cooking not only safer but, let's face it, much more fun. Whether you've spent £150 on a high-end knife or under a tenner on a dinky paring knife, keeping it sharp is crucial. 
Heres why I wasn't impressed at first. I only used it for a few minutes on each side, which resulted in nothing. I watched a video online with a master chef using his stone, and he sharpened his knife for 10 minutes on each stone before moving up to a finer grit. I took this hint, and used sharpened my knife on each side of this stone for 10 minutes, which led to perfection.
Using the strength of industrial high precision superior mono-crystalline diamonds, Diamond Machining Technology (DMT) have created a durable longer-lasting flat sharpening surface that will efficiently sharpen, hone, deburr and polish almost any type of knife or cutting tool. The DMT set contains 3 one-sided whetstones that have extra-fine, fine, and coarse grits which means you have a complete sharpening system at your fingertips.
Ceramic whetstones are meant to be used without water or oil, which means they can be used almost anywhere and are ideal for chefs or cooks who have limited working spaces. They will give you a very sharp blade and as their surface is very hard they will maintain their flat surfaces over the long-term, but as they have a fine grit, they can break if you drop the stone.
I use to work in the culinary industry and never finished my knives with a 6000-8000 grit (polishing) stone before. Mostly 2000 grit was good enough for me and I would usually run it by the stone every 2 weeks to keep the edge sharp. By no means do I see myself as a expert at sharpening knifes but it was a necessity and I can do it. I purchased this just to see if there was a difference and man is there. With a 2000 grit stone, you can still feel the burrs/slight edges that form from the sharpening process (especially if you didn't take care of your stone and formed a lot of uneven surface). You can see the removal of the burrs/edges after running your knife through this stone just on the first pass. It makes the knife buttery smooth and glide through food. Although I don't work in the restaurant business anymore, this stone has definitely improved the quality of my knifes and how I enjoy prepping meals at home.
The price of a whetstone is most often indicative of its quality, which directly correlates to how hard the stone is. “The more expensive stone, typically, is comprised of a harder material, which is efficient at grinding metal off of a good-quality knife,” Lau says. “It allows you to sharpen quicker [and] it allows you to sharpen a very high-quality knife, whereas a cheaper stone may not create a good edge if a knife is made from a very hard metal.” A well-made whetstone should cost $60 to $70.

I've only used it to touch up the edge on an ESEE RB3 and a pocket folder so far, but it has done very nicely for those tasks. I found that using the rounded edge works best for me in order to be able to run the length of the blade without hitting the leather lanyard. I'll hopefully try it out soon on fish hooks, too. A worthy and handy accessory, and cool looking necklace, to boot!
These are unquestionably great starter stones. After all the sharpening done over the course of a couple days, they're still perfectly flat, showing little to no signs of wearing down. Mind you I did watch tons of how-to videos online before undergoing the endeavor, so I knew how to try to make the stone wear evenly. But, my 15 year old nephew who was working on the Ontario, as I told him he could have it, if he wanted to fix it up, didn't watch all those videos and I didn't see any uneven wear on his stone after working it about a half hour either.
