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.
A sharpening stone is made of particles of abrasive material that are sintered or bonded together. The blade is moved across the stone and the steel is worn away, which creates the edge. However, at the same time, the stone is also worn away to reveal new, coarse particles. As a general rule, the softer the stone, the more rapidly it will wear and will be more aggressive in use. Harder stones don’t wear as quickly.
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.
Start off on the rough grit side of the stone. Check the grit on your stone, or the packaging that came with the stone, to identify which is which. In general, whetstones and diamond stones each have different grits on either side. The rough grit side is used to grind the steel down, while the fine grit side is used to sharpen or hone the knife. The grinding process comes first, so you start on the rough grit side.
For the common sharpening purpose, generally, people tend to use two phases. In the first phases, they use the coarse stone to shape the edges then jump to the finer stone. In application, these of the two phases can be extended with the grit stone in between. It might be varying in the number of grits or mesh in different types of sharpening stone.
The goal in sharpening a serration is to maintain the ramp of the serration right to the edge. You do not want to create an edge bevel. Therefore we once again recommend the trusty felt pen trick. Paint the serration to be sharpened and follow your process. Evaluate if you are removing all the black. It should not take more than 5-8 strokes to resharpen if your angle was correct. Rotate or spin the sharpener as you go for the most even, consistent sharpening.
The coarse stone will cut the metal off quicker but it is going to give you a rougher edge but that way the job gets done quicker, without the oil. It is not as messy. This is just a real simple set up. If you do wood work you can make a little wooden box and rout it out. In this particular case it is just a 2x4, stone traced out, finishing nails tapped down so they are deeper than the stone so when you drop the stone in, if you are at a workbench you can C-clamp it down in place or you can hold on to it.
I do have to question the grit ratings of these stones. I didn't notice anything before using them, but after a day, the 2000 grit actually felt courser than the 1000 grit side of the other stone. Whether that could be a byproduct of other factors or an indication of the more obvious, being that the grit ratings aren't accurate, I don't know. But that seemed to be the main criticism of cheaper whetstones, that their grit ratings often aren't accurate. Or maybe it's less a problem with accuracy and more a difference that most synthetic stones might have in common when being compared to much pricier natural stones?
first time buying a sharping stone. i bought this because i wanted to sharpen kitchen knives. you have to practice to get good at it, use a knife you don't care about because you might mess it up. there is some conflicting instructions online on how to use, water or no water. read as much as you can about using stones and practice, practice , practice. look up videos on youtube and internet. i had fun using it, BUY IF YOU WANT TO LEARN here is some stuff i found, they all sound like professionals http://video.about.com/culinaryarts/Sharpen-Knives-With-a-Whetston.htm?rd=1 http://culinaryarts.about.com/od/knivescutlery/ht/whetstone.htm this is a video that says don't use water http://video.about.com/culinaryarts/Sharpen-Knives-With-a-Whetston.htm?rd=1 this is a youtube video that i watched that uses water. *informative http://www.youtube.com/watch?v=KFIg9Cm-nJg
This coarse grit whetstone is great for prepping old and dull knives that need to be sharpened with a fine grit stone. One of my good knives edge looked like someone had tried to chop barbed wire. After ten minutes on each side of the stone, the edge was smooth and free of imperfections. After it hit the knife with the fine grit stone, I was cutting onions and apples like hot butter! I would soak this stone for 12-24 hours before using. It sucks water like a sponge. The surface needs to be damp when you sharpen.
Lubricant. Most knife sharpening experts recommend you use some sort of lubricant when sharpening your knife. The lubricant can come in a variety of forms, from water to oil. Most of the literature out there recommends mineral oil to be used for knife sharpening. The lubricant reduces heat from the friction that is created from sharpening your knife. Too much heat can actually warp your blade. Lubrication also helps clear out the debris, or swarf, that is created as you grind your knife blade on the stone. You can pick this up at most hardware stores for about $5. I used Norton Sharpening Stone Oil in the video.

Most of our sharpening stones are lightweight and portable, so you can use them at home or take them with you wherever you go.
Both Belgian Blue and Vielsalm Coticule are ancient stone layers found in the Belgian Ardenne Mountains with characteristics similar to both Novaculite and Siliciclastic sedimentary stone in that it is a metamorphic stone consisting of both gray and yellow volcanic ash mixed with tiny Spessartite Garnet crystals suspended in a clay matrix. However, due to its geology, both types of stone occur only in vertical seams sandwiched between two thick layers of bluish-purple slate and thus, they must be meticulously extracted mostly by hand. However, this type of extraction process is both very time-consuming and very labor-intensive and, quarrymen can only extract the stone for a few months each year due to inclement weather conditions. Consequently, both Belgium Blue and Coticule whetstones tend to be somewhat expensive.
A shinkansen is a Japanese-style pull-through sharpener named after the famous bullet train. It features two sets of ceramic wheels set at the right angle for sharpening a Japanese blade, which takes out the guesswork of the waterstone. Simply hold the handle with your left hand, then saw back and forth gently through the coarser wheel to sharpen, before switching to the finer wheel to polish.
Prior to using any kind of sharpening stone, it is advised that individuals soak the sharpening stone in light machine oil or household oil for at least 12 hours before being used. Before being used, it is advisable to wipe the surface of the sharpening stone to get rid of grime, grit or dirt that may have accumulated overtime during the time of storage.
I had wanted a pair of sharpening stones for a while, so was enthused to get this last week. I watched a bunch of YouTube videos on how to use them and a deburring strop I also bought and wow, my kitchen and pocket knives are now wicked sharp. Pro tip: if you post anything about it on social media, family and friends will almost surely volunteer their knives for more practice...
Historically, there are three broad grades of Japanese sharpening stones: the ara-to, or "rough stone", the naka-to or "middle/medium stone" and the shiage-to or "finishing stone". There is a fourth type of stone, the nagura, which is not used directly. Rather, it is used to form a cutting slurry on the shiage-to, which is often too hard to create the necessary slurry. Converting these names to absolute grit size is difficult as the classes are broad and natural stones have no inherent "grit number". As an indication, ara-to is probably (using a non-Japanese system of grading grit size) 500–1000 grit. The naka-to is probably 3000–5000 grit and the shiage-to is likely 7000–10000 grit. Current synthetic grit values range from extremely coarse, such as 120 grit, through extremely fine, such as 30,000 grit (less than half a micrometer abrasive particle size).
When you apply a sharp knife to the surface of a tomato, cucumber, carrot or other food item it should - if you are holding it firmly and applying minimal pressure - sink into the particular item without effort. As such all you really need to work on is your technique and making sure you keep your fingers out of the way. With a dull knife however things aren’t quite so simple. When you apply a dull blade to, say, a tomato it’s not going to slice into the skin. Instead the skin will be able to push back meaning you’ll need to apply ever more pressure to get the knife to penetrate. Increasing the pressure on the knife increases the likelihood of the knife slipping off the offending food item to one side or another. And if it slips to the side where your hand is attempting to hold the vegetable steady you could be in store for a very nasty cut. Because even a dull knife will cause injury if there’s enough force behind it.
The smaller the angle between the blade and stone, the sharper the knife will be, but the less side force is needed to bend the edge over or chip it off. The angle between the blade and the stone is the edge angle – the angle from the vertical to one of the knife edges, and equals the angle at which the blade is held. The total angle from one side to the other is called the included angle – on a symmetric double-ground edge (a wedge shape), the angle from one edge to the other is thus twice the edge angle. Typical edge angles are about 20° (making the included angle 40° on a double-ground edge). The edge angle for very sharp knives can be as little as 10 degrees (for a 20° included angle). Knives that require a tough edge (such as those that chop) may sharpen at 25° or more.
If you’re sharpening high quality knives, you probably don’t want to use a cheapo sharpening stone. But if you’re just getting started with sharpening your pocket knife, there’s no need to get too fancy right off the bat. You can find a sharpening stone at most hardware stores for about $10. This one is very similar to the one I use. Nothing fancy. Most basic sharpening stones come with two sides: a rough grit and a fine grit. The finer the grit, the finer or sharper you can get your blade. You usually start off sharpening on the rough grit and then finish sharpening it on the finer grit.
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.
Frequently, our recommendation for beginning sharpeners is to start with diamond stones as their strengths make them ideal to build a sharpening toolkit around. Diamond stones are low maintenance and durable, lasting many years with only occasional cleaning. They are among the fastest stones to use making them time efficient. Diamond grit will handle even very hard steels, and diamond stones can be used for flattening waterstones. All these things make diamond stones a practical foundation for your sharpening toolkit.
Oilstones, like the Norton whetstone, can be made out of natural or synthetic material like Novaculite, Aluminium Oxide, or Silicon Carbide. As per the name, oilstones require the use of oil as you sharpen your knife's blade. This type of stone is slower at sharpening or honing a blade and it can be messy and you need to always have some oil on hand but it creates a nice sharp edge and a beautiful polish.
The unique three stone system features a 6" medium Arkansas, 6" fine Arkansas and 6" coarse synthetic stone mounted on a molded plastic triangle with handles on the end for easy stone selection. The sturdy molded plastic base has non-skid rubber feet for safety, a V-shaped trough to catch oil drippings and easy-to- read stone identification markings.
Whetstone sharpener or sharpening stone has been here and there for a long time even before we born in the form of natural stone whatever they look like. Until today, the natural stone likely to be the most preferred options to sharpening things because of their versatility. As the technology improves, there are immerging new models and we are now not only having an option to the natural stone, but there are also other types considered better and more practical to use. The arrays can be bewildering to the inexperienced sharpeners that so often times many of them end up with a crap or wrong decision on stone type for their utensils.
Actually, the company contacted me to make sure I received the stones and that I was happy with them. Excellent service. The stones are great! I'm pretty much a novice so the clear instructions that came with the stones and the eBook instructions were wonderful. The eBook had quality pictures demonstrating the use of the stones and the written instructions were clear and to the point. Within minutes of opening the box I had the stones figured out and sharpening my AF survival knife, my pocket knife and a couple of my wife's kitchen knives...which included a very expensive chef's knife. Very satisfied with this product and highly recommend it.
The word “Novaculite” is derived from the Latin word “novacula”, which means “razor stone” and is essentially a metamorphic, recrystallized, variety of Chert composed mostly of microcrystalline quartz that is found in the found in the Ouachita Mountains of Arkansas and Oklahoma and in the Marathon Uplift of Deposited in the Devonian Period and the early Mississippian Subperiod some 410 to 325 million years ago and subjected to uplift and folding during the Ouachita orogeny of the Atokan Epoch (early Pennsylvanian Subperiod), Novaculite is a very tough stone that is resistant to erosion and thus, the various layers of Novaculite stand out as ridges in the Ouachita Mountains. Thus, due to both its availability and its composition, it has been mined since ancient times for use as arrowheads and spear heads as well as in more modern times for use as sharpening stones.
So, as you can see, there are numerous different types and grades of whetstones on the market today and each has its advantages and disadvantages. Therefore, the right practice to choose the right sharpening stone for you is to choose a whetstone material based upon how fast you need to remove metal and how fine an edge you need. For instance, although they are often the most expensive type of whetstone, diamond hones generally cut the fastest even in their finer grits followed by Crystolon Stones and then India Stones which are then generally followed by Japanese Water Stones and then by Novaculite, Belgian Blue, and Coticule whetstones in terms of how fast they remove metal. However, it should also be noted that the rougher an edge is, the less sharp it is while, the more polished an edge is, the sharper it is and thus, rough edges are fine for some tools while other tools require a much finer edge and, hunting knives require the finest edge of all. Therefore, the trick to choosing the proper whetstone for any given sharpening purpose is to purchase multiple stones with varying grits to accomplish each given task from cutting an initial bevel or defining a damaged edge to refining an existing edge to polishing it.
