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]

Very quickly, we gravitated toward the ceramic rods, which all performed well on both types of blade; the steel honing rods created tiny chips on the Japanese blades. That’s because steel honing rods are made of exceptionally hard metal covered with fine ridges. These ridges bend softer German knife edges back into alignment, but harder Japanese knife edges have a tendency to break rather than bend. The ceramic rods also provided a very slight stickiness or friction when honing that made it easier to sweep the blades in smooth strokes, as you’re supposed to. Steel hones feel slick—the blade wants to slip instead of glide—and that makes them a bit trickier to master. And for the reasons above, the Idahone rapidly became our favorite among the ceramic rods. We’re also not alone in liking it: It’s extremely well-reviewed on Amazon and is recommended by many specialist knife retailers, including Chef Knives To Go, Epicurean Edge, and Knife Merchant.
Chefs will do this every day, and there's no reason you shouldn't too. Before cooking, or after you've done the washing up, honing your knife will help keep it in good condition. "When you're using a honing steel, you're not actually removing any metal at all, just re-straightening that edge, to get it back in line," says Authbert. Remember that you'll still need to sharpen it every two or three months.

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.
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. 
To summarize, Shapton Glass 500, 1,000 and 2,000 is a good combination and if you would like to throw in the 4,000 grit stone in lieu of the 2,000 that is good as well. If your knives are very hard, ZDP 189 for example, this is a fantastic choice. (They are also excellent for tools, chisels etc. and they are the premier choice for many Straight Razor honers).
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...
Although the Trizor XV is easy to use, you have to use it correctly. That means sharpening one side of the blade at a time until a burr forms, whereas a back-and-forth, one-side-and-then-the-other approach might seem more intuitive. (Don’t worry—the Trizor XV’s manual explains the process plainly.) Maintenance is easy: Once a year or so, you open the bin on the machine’s underside and wipe out the metal shavings that it has conveniently captured there with a magnet.
Scissors get dull, too, but many sharpeners can’t handle their unique shape. This easy-to-use manual sharpener can handle scissor easily, and will also sharpen all of your non-serrated knives with ease. It’s ergonomically designed for either right- or left-hand use and has a protective finger guard so you can safely sharpen all the knives in the block.
The M3 uses a tapered diamond sharpening rod to effectively restore the cutting performance of your entire knife set. Swap out the diamond sharpening rod for the ceramic honing rod and you can easily put a razor-sharp finish on your knives. The handle incorporates a 17° angle that sets the knife in the proper position for consistent passes along the rods – the key to achieving a sharp edge along the entire length of the blade. It’s that simple – you’re ready to start enjoying your culinary experience with sharp, precise cutlery that’s a joy to use.

using an appropriate blade for the task – a thinner blade for more delicate work, and a thicker blade whenever a thinner blade is not required (e.g. a thinner blade might be used to cut fillets, butterfly steak or roast for stuffing, or perform Mukimono, while a thicker one might be used to slice or chop repeatedly, separate primal cuts of poultry or small game, or scrape and trim fat from meat or hide, as these actions would be more likely to cause unnecessary wear on a thinner blade.)
If you’re a dedicated home chef, or if you simply demand the best possible edge that doesn’t involve messing with stones or jigs, we recommend the Chef’sChoice Trizor XV Sharpener. Cook’s Illustrated also names this professional-grade electric model as the top pick in the category, and I’ve used a similar model, the 1520, to great satisfaction on my heavy Wüsthof chef’s knife and cheap paring knives for six or seven years now. (The fact is, Chef’sChoice dominates the high-quality sharpener market.)

Once sufficiently wet, it's time to position the stone on something solid, so it doesn't move about during sharpening. Many come with holders, but you can just place it on a slightly damp tea towel on the table. The stone should be roughly perpendicular to your body, though Warner told me it is sometimes easier to angle it ever so slightly to the right (if you're right handed). 
This article is not about how to sharpen a knife, check this article instead, but briefly, a coarse stone is critical, it has the potential to raise a Burr quickly and make a dull knife sharp quickly. The correct use of pressure enables us to form a burr, remove the burr and then do some coarse stone refinement and thus create a very sharp knife. This sensation is motivation, it is a confidence builder and will enhance your sharpening experience, so believe me when I say that a coarse stone is your first priority. I recommend a 400, 600 or 800 grit. After that, depending on the knives you are sharpening strive to obtain stone combination, such as a 400 – 1,000 – 5,000 grit three stone combination is going to allow you to achieve knives sharper than most people have ever seen.

Manual sharpeners are, in my opinion, the best way to sharpen your knives. They are my personal favorite, because they allow you to sharpen your blades with precision. Unlike electric sharpeners which can take off layers of steel so quickly you barely see it happen, you maintain control over the sharpening process with a manual sharpener. You can put one pass through, then check your edge. You can do another pass or two, then check it again.
Furthermore, Novaculite consists of several different layers of stone of different densities, grit sizes, and colors. Thus, the red Novaculite layer (aka Washita Stone) is the both the softest and most coarse while, the next most coarse/hard grade is the grey/white Soft Arkansas stone; both of which cut relatively fast for a hard whetstone material and thus, they are an excellent choice for refining a bevel. Then, the next grade of coarseness/hardness is the hard Arkansas stone which is used to polish the bevel rather than define it and, last there are the grades of Hard Black and Hard Translucent Arkansas stones which are used for extremely fine honing and polishing of a cutting edge. Plus, it’s also the primary material in “Charnley Forest” (English) and “Turkey” oilstones.
The days of visiting the knife sharpener are gone. It is rare that you will see a knife sharpening truck roaming the streets, dinging its bell, on a search for customers. Those days are gone because newer, easier methods of sharpening knives have been developed. You no longer need to know special techniques and methods to properly sharpen a knife. You don’t need to worry about holding your knife at the perfect angle to get a nice straight edge.

The Arkansas Novaculite stone has earned the reputation of the most sought-after natural abrasive worldwide and is a premiere sharpening product used not just as a knife sharpeners, but as woodworkers, jewelers, surgeons, dentists, veterinarians, die makers, gunsmiths, and goldsmiths. Other applications: calibration of x-ray crystallography machines and maintenance of ice skate and snow ski’s.
The surface of these types of metal alloys will not discolor due to rust or other oxidation. These special alloys are different to carbon steel because they are metals that have an active-passive nature. Nevertheless, they can often rust—although you may not notice it. Food residue or water can allow rust to form in places where oxygen cannot easily reach. Rust can quickly penetrate near the blade tip, so wash your knife in a detergent solution after use, then dry it with a towel and store it in a dry place.

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.

Modern synthetic stones are generally of equal quality to natural stones, and are often considered superior in sharpening performance due to consistency of particle size and control over the properties of the stones. For example, the proportional content of abrasive particles as opposed to base or "binder" materials can be controlled to make the stone cut faster or slower, as desired.[7] Natural stones are often prized for their natural beauty as stones and their rarity, adding value as collectors' items. Furthermore, each natural stone is different, and there are rare natural stones that contain abrasive particles in grit sizes finer than are currently available in artificial stones.[citation needed]
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.
It is designed to help sharpen straight bladed knives that are made of steel. It cannot be used on ceramic and serrated edges. The two sharpening modes guarantee the user gets the best service from it. It has been designed with the users’ safety in mind. This is due to the large grip handle and the non-slip feet. It has an attractive design that makes it a great addition to any kitchen.
Now hold the handle of the knife firmly in one hand and, with the blade facing you, place it on the sharpening stone at an angle of 10 – 20 degrees. Make sure that there is a gap less than a 1/4 inch between the back of the blade and the sharpening stone. Place your free hand on the blade, but never directly on the cutting edge. We are pretty serious about this one. Touching the cutting edge can lead to some serious injuries so please be careful.

These are very popular stones. 8" Dia-Sharps have a single grit per stone making them more expensive, but at 8" by 3" they are wider than the 8" DuoSharps, offering a good working surface. The 8" Dia-Sharp line also has the widest range of grits available from DMT, with extra extra coarse, medium extra fine and extra extra fine options not available in other sizes, so it is good line to consider. One coarse and one fine stone is a good starting point.
