Basically, there are 3 types of whetstones, Arato (rough grits), Nakato (medium grits) and Shiageto (fine grits). We normally use Nakato for the sharpening, but you can start with Arato to correct rough or damaged edge, and then Nakato and finish with Shiageto to get a fine and keen edge. All the sharpening methods and processes are same. However, it is not recommended to sharpen the opposite flat side of the blade with Arato

This device will fulfill all of your needs in the kitchen. For instance, it is capable of sharpening American and European blades, as well as Asian knives! Of course, it doesn’t stop there either!

This mighty, sleek model from Buck knives has a diamond coated sharpening surface teamed up with one fine sided 1200 grit, a 750 medium and a 325 grit coarse side. The tapered handle allows firm control and ultra light weight gives it amazing mobility. Overall, it’s certainly a brilliant sharpening equipment for achieving extreme sharpness on short blades and tools.
With our sharpeners in hand, we went about putting them to work—meaning we needed a lot of dull knives. Those are in short supply in the Wirecutter test kitchen (Lesley keeps ’em sharp), so we borrowed some from coworkers and sacrificed a few of the test kitchen’s blades. To ensure truly, appallingly dull blades, we ground their edges repeatedly against a piece of concrete curbstone.
I bought this and Unimi's 600/1000 whetstone at the same time. Curiously, reviews are currently blocked for their 600/1000 model, as amazon wouldn't let me leave one for it. Considering the conspicuous absence of reviews in the other stone's listing, one can only assume they're being censored for everyone. So, maybe I should be more critical of these stones, and use them a while longer before giving them any praise? But I've had a very positive experience with them so far, and the 600/1000 stone was the one I found most useful.
Our large selection of stones from many well-known manufacturers will allow connoisseurs to find the ideal stone for their needs. Because all manufacturers formulate their stones to emphasize a different mix of qualities, and because these qualities can vary widely between different stones, most woodworkers choose stones from several manufacturers to build up an optimal set of sharpening stones. Then again, once you get to know the characteristics of certain types of stone, you may find one supplier who will provide all the stones you need. Sometimes this can be an advantage. But there is no one size that fits all; each stone must fit your needs and work style.
These particular types of sharpeners can be used for various knife varieties, but they’re most commonly utilized for kitchen knives. There is no doubt that having one of these sharpeners readily available in your kitchen can be very advantageous. When choosing one of these sharpeners, make sure to choose a good brand, such as Chef’s Choice or KitchenIQ.

Learning sharpening technique requires focus even without worrying about the stone itself. Stones that require frequent flattening, soaking and cleaning, or that take a long time to create an edge can be a source of frustration to some beginning sharpeners. Keep in mind your willingness perform regular maintenance when choosing a starting set of stones.

Storage Allotment – How much space are you willing to allot to your knife sharpener? Although this won’t be such a big deal for some individuals, it will be a major selling point for others. By choosing a smaller product, such as the Chef’s Choice Pronto or the King Sharpening Stone, you will be able to toss your sharpener in a drawer and forget about it, until you need it again. On the other hand, a bigger product, such as an electric or entire sharpening system, will require increased space. Be sure to choose an option that fits your preferences.

Very interesting. If you work flat, 45 degree is what I was taught. Love the wet stones, especially the oiled ones. The nice thing about the leather part, is the mirror finish on a razor sharp blade which is a must if doing fine wood working, carving etc. A rough blade simply does not have the fine detailed dexterity. I find that the oiled sandpaper can work great as well, but found that the refined clay bars (white refined fired clay rounds and flats etc) does a wonderful job of keeping those razor edges refined, smooth as possible and then one can high polish them for smooth cutting. Believe me, when working wood for a flute, one wants that refined edge.! Learning how to hone a blade on a flat surface teaches one to work outside without a table/wall handy too...:) But we all have to start somewhere!:) Anyway, great stuff and a great start for those who want more from their tools!:) Cheers!

Like all the other Chef’s Choice products, this too is a super-fast, super-efficient kitchen knife sharpen, ideal for regular use. This advanced electric diamond sharpener is a one-stop solution for a wide range of knives such as serrated, doubled-edged, short and straight blades. The flexible stropping discs help to engineer mirrorlike, glossy finishing touch on the edges.
This was given to me as a Christmas present and might be ok for any cheap dull knives, but if you care enough to seek out a whetstone and have good quality knives, you'll probably know to go elsewhere. The grit rating is not provided for either side, on the packaging or website so, you'll be taking a chance. For decent quality knives you'll probably need 1000/3000 to get them razor sharp or 1000/and below if you knives are really blunt.
