There is no dominant standard for the relationship between "grit size" and particle diameter. Part of the difficulty is that "grit size" is used to refer to the smoothness of the finish produced by a sharpening stone, and not just the actual size of the grit particles. Other factors apart from particle diameter that affect the finish (and thus the "grit size" rating) are:
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.
If your knife is dull, we advise you to start with the diamond stone. After restoring the edge to original shape, de-burr the edge lightly with the ceramic stone in order to get a razor-sharp edge. Use no oil or water. Start by laying the blade flat on the stone, raise the blade spine approx. the thickness of the blade, and start moving the knife in circular motions.
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.
Cutting angle – With a manual stick or sharpening stone you set the angle yourself so this does not factor into the equation when choosing that type of sharpener. When shopping for an electric sharpener however it does. You’ll want to decide if you want your knives to have the 15 degree “Asian” style angle so that you can make precise cuts or the Western standard 20 degrees or 22-degree sharpening angle. Most people will opt for the 20 or 22-degree angle simply because their cuisine doesn’t call for a lot of finesse from their knives and those knives are probably of a heavier Western variety anyway.
The stones from Shapton are probably the hardest of all Japanese sharpening stones. They will remain flat for a long time. They are therefore the best choice if you are looking for a relatively coarse stone that cuts quickly without having to be dressed repeatedly. The finer-grained stones also work very well. But Shapton stones do not provide the mirror finish you can achieve with softer stones.
Put the pointed, narrow end of the sharpener up against the open end of the gut hook. The narrow, pointed end of the sharpener should face in toward the thickness of the blade, away from the edge of the gut hook. Match the angle of the sharpener to the original edge angle. This will maintain the correct sharpening angle and prevent you from getting cut by the blade tip. Hold the same angle when sharpening each side of the gut hook.

One of the combinations of stones that I was introduced to several years ago is a unique one, it is a 500, 2,000 and 16,000 grit combination. I was apprehensive when I first tried this, that was thousands of knives ago, it works, it is fantastic combination. It is unique because the traditional way of thinking is that we should be doubling the grit sizes as we sharpen, for example, a 500 grit stone should be followed by a 1,000 grit, then 2,000 grit. This line of thought is meant to be flexible, it is a general rule only, I have broken it countless times.
Practice holding the knife at a 20 degree angle. Most straight blades need to be sharpened at a 20 degree angle. To find the angle, hold the directly in front of you so it's straight up and down. This is 90 degrees. Tilt the knife halfway towards the table so it's at a 45 degree angle. Tilt the knife halfway again so it's about an inch (2.5 cm) above the table. This should be a 20 degree angle.[4]
It helps you get the knack for a consistently correct angle BUT the idea falls apart a bit when it comes to the curve and taper part of the knife and if your knife has an excessively narrow (slicer/boner) or wide (cleaver) width. It will also mark up the sides of your knife which may bother some who are obsessed with the cosmetic appearance of their $150+ Japanese knives--I could care less.
The speed and polishing ability of waterstones attract many sharpeners. Waterstones sharpen quickly and are available in fine polishing grits not found in other stone types. The ability to flatten the stones is a necessity when sharpening with waterstones, so a starting set should include a flattening stone of some kind. Our article, How to Flatten a Waterstone, has more information about keeping waterstones flat.
To use Al's method, take a black felt pen and shade in the bevel of the knife. Then take two strokes on the stone and examine the edge. If you have maintained the proper angle then all the black will be gone. If you see black on the top of the edge it means you are holding the back of the knife too far from the stone. If there is black on the bottom of the edge but the top is clean then you are laying the knife too flat on the stone and you need to raise it a bit. Repaint the edge and try it again. Once you discover what the right angle looks like then just maintain that.
The toughest angle to master is the angle at which you'll sharpen the edge of the knife. For a Japanese knife, that should be around 12-15 degrees. Before you reach for the protractor, a good test is to get roughly half an index finger's gap between the spine of the knife and the stone (see above). Remember to remove your finger before you start sharpening. For a Western-style knife, you want an angle of about 20°, so raise it ever-so-slightly higher.

if you have regular kitchen knives it will not work- first its to deep and the blade does not stick out, not dinner knives but cooking knives. of all the knives i put in it only 1 was wide enough to stick out. the device does not hold the blades. all the blades tested fell out of it, even a hunting knife, maybe its for 1 type of knife and they are selling it as the must have tool for all.. that said sell something useless for a few bucks that most cant use, they got a few bucks that most will blow off and not worry about a refund.. DONT WASTE YOUR MONEY.

Vielsalm Coticule on the other hand generally occurs in much more narrow layers sandwiched between the slate layer and the Belgian Blue layer and thus, it is both less plentiful and more expensive than Belgian Blue stone. Also, Coticule is divided into different grades and sometimes displays blemishes on the surface due to its proximity to the slate layer. Furthermore, it is somewhat harder than Belgium Blue stone and, due to its brittleness, it is bonded to a substrate layer of hard slate prior to sale to prevent the stone from breaking during use.
The Sharpening and Specialty lines of waterstones from Naniwa are available in several packages of three to five stones. The Specialty line is the same as the Sharpening line, but half the thickness and therefore less expensive. Both the Sharpening and the Specialty stones are 8 1/4" long by 2 3/4" wide, amply sized for most knives and tools. These are a higher grade stone that do not require soaking before use. While you would need a flattening stone in addition, these kits are a good way to enter into premium grade waterstones.

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.
It is better to understand the difference in sharpening stone materials before you are going to make any decision. Among the available options in the market today, Waterstone, oilstone and diamond stone are the most common type of sharpening stone. Each of stones comes with advantages and disadvantages. Waterstone and oilstone are available in natural and synthetic models. Synthetic are the most common and easy to find as man makes them. As the use of natural stones (e.g. original Arkansas or Japanese natural whetstones) is has diminished in popularity, they are beginning to rare in the market. Artificial stones have a more consistent particle size and controlled with a tight mechanism in providing high-quality sharpening stone.
In most cases a sharpening stone will be a combination of sharpening grains and a binding agent. However, in case of a Ardennes Coticule it is a completely natural product. The grains have cutting edges which enables them to sharpen your knife. As soon as a sharpening stone is used little pieces of the grains break off, revealing a new cut ing edge. The higher the number, the finer the grain. Stones with coarse grains (up to grain 400) can be used to shape the blade of a blunt knife. You can subsequently take care of the fine finish with a stone with a smaller grain.
A: We’re all told that a sharp knife is safer than a dull knife yet most everyone knows that merely touching a sharp knife can often result in a painful cut while we can wrap our hand around a dull blade with little worry. So why would anyone in their right mind claim that a sharp one is safer than a dull one? To a certain extent it’s a matter of semantics for sure, because there is no denying you have to be extremely careful around really sharp knives. But at the same time there is a very good reason to consider a dull knife to be more of a safety hazard than a sharp knife.
Unfortunately, the arrays of modern whetstone 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. The most difficult to determine is whether the whetstone is fake or fabricated with low quality of materials. To avoid this you can only go for the reliable brand of a whetstone.
Be careful: Don’t move your fingers laterally along the edge, you’ll cut yourself. Feel for a rough area running from tip to heel. Again, it takes time to know what to expect because the best burr will be subtle. Just know that the bigger the burr, the more metal you are removing—more than necessary. Don’t worry, you won’t ruin the knife doing this. You’re learning here, and mistakes are part of the sharpening journey. Learn from them.

Honing is kind of like dusting the furniture while sharpening is more like reupholstering the furniture. Honing is purely a maintenance activity that should be regularly practiced to make sure the blade is clean and sharp as can be every time you use it. It’s easily done using a honing rod, a leather strop or a sharpening stone; as most stones have a side for sharpening and a side for honing. Honing is akin to trimming your hair to remove the split ends. It’s not a full on haircut. What it does is realign the tiny sharp protrusions along the edge of the blade that can be bent over with use, so that they stand more or less straight.
Some stones need water, while other stones need oil for floating the swarf (small metal filings created when sharpening) away. Simply apply a few drops of either oil or water directly to the stone. (We recommend using an inexpensive spray bottle for applying the water.) The lubricant you need is determined by the type of stone you are using. Water stones and diamond stones require water. Oil stones such as India, Crystolon and Arkansas stones use oil for a lubricant.
Table mounted device – Typically the manual powered table mounted sharpener looks virtually identical to the electric powered sharpener with a slot for each stage. Where they differ is that each slot in the manual powered sharpener has only one groove and you pull the blade through this groove toward you to sharpen the blade. Once the blade is sufficiently sharp you place it in the honing groove to refine the edge and pull it toward you again several times. If there is a third, cleaning, stage you repeat the process for that stage as well.
Method 1: Use an Electric Sharpener. Quality electric sharpeners are an option, but I strongly discourage their use. First off, they remove a tremendous amount of material from your edge. Sharpen your knife a dozen times, and you've lost a good half-centimeter of width, throwing it off balance, and rendering any blade with a bolster (i.e. most high-end forged blades) useless. Secondly, even the best models provide only an adequate edge. If you don't mind replacing your knives every few years and are happy with the edge they give you, they'll do the trick. But a much better choice is to...

Begin with your lower-grit stone. Place the heel of your knife on the far edge of the stone, holding the blade gently but firmly with both hands at a 15- to 20-degree angle. Using even pressure, slowly drag the knife over the stone toward you down the length of the stone while simultaneously moving the knife such that the contact point moves toward the tip of the blade.

Your stroke can be straight or circular, from "hilt to tip" OR "tip to hilt," whichever is more comfortable. If you're using a small portable sharpener, stroke the blade in nearly a straight direction. Remember to always cut into the stone and never pull or drag your edge backwards. The blade edge should face in the same direction as your stroke. So, you're essentially moving the metal away from the edge. We recommend the circular stroke as it helps you maintain your angle instead of having to find it every time you lift the knife from the stone.
Japanese water stones – both natural and synthetic – are known for their superior sharpening performance, not only for Japanese tools, but also on their Western equivalents. The loosely bonded abrasive grit is washed out very quickly, as it blunts during the sharpening process; this exposes new, sharp, particles that can get to work on the blade. Water stones are lubricated only with water! Never use oil! 

The Whetstone 2-Sided Sharpening Stone is made from professional grade corundum and will sharpen everything from a razor blade to a cleaver and even a machete, should you happen to have a machete lying about that needs sharpening. This is the simplest type of sharpener it’s true but the company have obviously put a great deal of thought into the product.
Understanding Grit: You’ll see a bunch of numbers being thrown around when discussing the grit of a sharpening stone. The number refers to the size of the grit. The larger the number, the finer the grit. A good beginner stone would be a two-sided stone with #400 and #1000 grit. The #400 grit is the courser stone for working out the nicks and imperfections, the #1000 grit is for refining.

Speaking of building muscle memory, here is a good exercise for you, a confidence builder: Paint the edge of your knife and bevel with a Sharpie and sharpen the knife at an angle that results in the removal of that Sharpie. In many cases it will be close to the 20 deg angle anyway. When you have achieved success, repeat the process and do that ten times. Now flip the blade over and do it on the other side, you don’t need to use much pressure here, just a little. You want to get to the point where you can place the knife at the SRA “Sharpie Removal Angle” the first time, every time.
