With its premium series Select II, the whetstone manufacturer Sigma Power Corporation from Tokyo addresses users of high-alloy steels such as HSS. These stones, too, are obviously intended to engender a grinding experience similar to that of natural stones. The special production process is expensive, but the Sigma Select II probably has no equal when it comes to demolishing steel.
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.
I purchased this set together with the 400/1000 grit stone assuming that some of my knives were quite dull and would need work on a coarse grit stone. Premium Whetstone Sharpening Stone 2 Side Grit 400/1000 | Knife Sharpener Waterstone with NonSlip Rubber Base & Flattening Stone. This is my first wetstone. First off I tried to sharpen my Chicago Cutlery boning knife. This knife is nearly thirty years old, has been abused in may ways and was quite dull. It was very difficult for me to get a burr on this blade, which I attribute to poor technique. Next I moved on to my Henckels Professional S paring and chef's knives. The paring knife was moderately sharp and was modestly improved after working over all three grits of stone. It would cut paper but again it was difficult to develop a burr with this blade. Undaunted I switched to the chef's knife. This knife is twenty years old and has never been professionally re-sharpened. I have sharpened it twice with a Lanksey sharpening system which marred the finish but did put a good edge on the blade. Lansky Standard Coarse Sharpening System with Fine Hones. The chef's knife was moderately dull and had several pits visible on the cutting surface. I modified my technique for passing the knife over the stone and worked the chef's knife over the 400 grit stone aggressively and eventually I was able to get a burr to form from the tip of the knife all the way to the handle. From there it was a simple process of reforming the burr on the 1000 grit stone and then finishing on the 6000. After sharpening, the chef's knife easily and cleanly slices a tomato with very light pressure and is in my opinion very sharp. Not sushi knife sharp but more than enough for the chopping and slicing I expect of it. I'm looking forward to going back and working both the boning knife and the paring knife over again. Don't expect a good result from this product the first time you use it. Watch videos on using a wetstone, expect to spend at least twenty minutes per knife at first, and practice forming a burr. If you can form a burr, you will be able to successfully sharpen your knife.
When starting out sharpening, it won’t be long before you hear about the “toothy” vs “polished” edge. It will suffice to know that a 1k stone is going to give you an edge that will perform beautifully as will a knife finished at 5k. There is a belief that a knife that has a highly polished finish, 5k and up will be so polished that it’s toothy goodness will be erased. This knife will not bite into the skin of a tomato for example because the edge is too polished, it will slide over the top. This is not always true, if the knife has been sharpened well, i.e. if Side A and Side B of the blade meet precisely at the Apex of the knife, that edge will slide into a tomato quite beautifully. I have seen many brand new Japanese knives with highly polished 8k edges that no tomato skin can stand up to.
Manufacturer contacted and sent a new one for replacement. Great customer service but replacement item was nicked on the corner. It was still usable so i didn't bother to ask for another replacement. I would recommend item to be shipped in another box instead of an over-sized yellow envelop which is not adequate protection. Item sharpen my knife pretty good though..

Silicone Carbide whetstones on the other hand, are the fastest cutting of the three types of oil stones and the stones made by Norton are called Crystolon Stones. Also they too are graded as either fine, medium, or coarse stones depending on their grit. But, although these stones will not produce an edge as fine as Arkansas Oil Stones or India Oil Stones, their fast cutting ability makes them ideal for sharpening tools as well as for cutting the initial edge bevel on extremely dull knives or repairing the edge on damaged blades. Last, because they sharpen so quickly, it a common practice to start with a coarse Crystolon Oil Stone and then progress to either a medium or fine India Oil Stone and then to finish with an Arkansas Oil Stone.


I've been using this stone for months and have started to find that, while the fine side does provide a nice sharp edge, the 400gr side is wearing my knives unevenly, which causes me to be unable to finely sharpen the entire length of the blade when moving to the fine side. The logo that is put in the middle of the 400gr side of the knife is causing more material to be removed than the rest of the blade when I'm sweeping across. I even verified this by going straight down the length of the fine side and watching the wear pattern come from the material coming off of the knife onto the stone.
A good whetstone and a little practice will keep all of your knives sharp and in perfect condition. The beauty is that it doesn’t take much effort to learn, just a good bit of practice to get the angle right and keep a consistent angle while you’re sharpening. Whetstones are available in department stores or online, and while they range in price based on the fineness of the grit, this thread at eGullet can help you pick a good grit to start with.

Low Grit Stones: A sharpening stone with grit number less than a 1000 is generally used for knives and tools that are damaged. If your blade has any nicks or chips in the blade, the stones will take care of them in a jiffy! They usually have a coarse side for nicks and chips, with the other side for general sharpening. Even if the knife’s edge has become totally blunt, the stone will re-sharpen it perfectly.
Some of the videos I watched suggested soaking the stone for 12-15 minutes prior to use. One suggested using vegetable oil on the surface versus water/soaking (I used water and presoaking it for 15-minutes). So instead of a simple 'out-of-the-box-and-use' approach, it required a bit of research before sharpening a knife. Otherwise I would have given this product a 5-star rating.

I've always wanted to sharpen knives on water stones, and this set gave me the motivation to finally give it a shot. The price is amazing for the quality and content of the set. It comes with all the grits you need to sharpen anything... I usually start on the 400 grit if the knife is very dull, or directly on the 1000 grit if it's not too dull. The 3000 and 8000 grit stones are softer and ideal after the coarser stones. The online learning section is truly amazing, much better than I expected. A convenient place with instructional videos and many articles about knife sharpening. Only downside is that the knives are now so sharp I need to be very careful using them... but that's a good thing! I feel like I fell in love with knife sharpening again.

"Sharpening is like a hangover cure," says Laurie Timpson, founder of Savernake Knives in Wiltshire. "If there was a cure and you knew about it, I'd stay at your house, crash on your sofa and have whatever it was when I woke up. Everyone would have it and there'd be no discussion. Everybody says they've created a perfect sharpening technique, and they haven't." 
Grinding is generally done with some type of sharpening stone. Sharpening stones come in coarse and fine grits and can be described as hard or soft based on whether the grit comes free of the stone with use. Many sources of naturally occurring stones exist around the world; some types known to the ancient world are no longer used, due to exhaustion of former resources or the ready availability of superior alternatives. Arkansas, USA is one source for honing stones, which are traditionally used with water or honing oil. India is another traditional source for stones. Ceramic hones are also common, especially for fine grit size. Japanese water stones (both artificial and natural) come in very fine grits. Before use, they are soaked in water, then flushed with water occasionally to expose new stone material to the knife blade. The mixture of water and abraded stone and knife material is known as slurry, which can assist with the polishing of the knife edge and help sharpen the blade. Generally, these are more costly than oilstones. Coated hones, which have an abrasive, sometimes diamonds, on a base of plastic or metal, are also available.
Let’s start with Arkansas. If you have heard about Arkansas oilstone, it uses the Novaculite stone that mined in Arkansas. The most expensive of Arkansas stone is the Hard Translucent model that begins to rare in the market. If you want to shop for Arkansas, they are available in different grade starting from Soft Arkansas, Hard Arkansas, Hard Black Arkansas and Hard Translucent Arkansas. The finest grade of Arkansas can shape such of mirror polishing edges.

The sharpener is simple in concept, solid in its fabrication and reliable in the way it goes about its business. The design is also free of right-hand bias which is good news for the lefty chefs out there.
Beginning on the right side of the knife, move from tip to heel and heel to tip, then flip the knife and repeat. For the left side, it’s opposite—start at the top of the stone to reach the heel area completely. So, you will move from heel to tip and then tip to heel. Remember to apply and release pressure as you did earlier, exactly the same as in Step 2, but with light, refining pressure.

But it's a different type of sharp, according to Joe Authbert, product development manager at ProCook. "What it does is add tiny little micro-serrations onto the edge of the blade." But fear not - your smart knife won't end up looking like a bread knife, as you'll be hard-pressed to spot the serrations. "If you looked at it under a microscope, on the cutting edge, there are these little lines that generate the sharpness, rather than a waterstone which is a smooth sharp edge," says Authbert.
