The basic concept of sharpening is simple – you're using an abrasive edge to remove metal – but the knife you buy may alter the method you should use. A general rule of thumb is that a waterstone can be used for both Japanese- and Western-style blades, but you should avoid pull-through sharpeners for Japanese knives (or any knife with very brittle blades).
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.
Meanwhile, if you want something that you can use to sharpen a variety of knives and edges, including small and pointed tools, you might want to consider the DMT WM8CX-WB 8-Inch Duo Sharp Plus Bench Stone – Coarse/Extra Coarse with Base. For less than a hundred bucks, you can even use it to repair a damaged edge because of its extra-coarse diamonds.
Similar to electric sharpeners, manual sharpeners simplify the entire sharpening process. However, they tend to have fewer slots for sharpening. One benefit of manual or handheld sharpeners is their portability. Their manual operation, combined with their small size, makes it convenient for cooking professionals who are always on the move. Depending on how the manual sharpener is designed, you can either draw your knife between the slots or the sharpener is moved along the blade of the knife. Whichever type you choose, manual sharpeners easily sharpen a blunt or dull knife, to the desired level of sharpness.
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.
Every few months, you'll notice that your chef's knife has a harder time yielding perfectly thin slices and precise dices. You might even find your knifework is slipping—literally. And aside from being annoying to cut with, a dull knife can be seriously dangerous. To keep your fingers (and your dinner) in good shape, you'll want to learn how sharpen a kitchen knife by using a whetstone or a sharpener, and maintain that edge by honing it with a steel rod.
A: People often make the mistake of assuming that just because a mechanical knife sharpener will sharpen the edge of a knife that means it will sharpen any type of cutting edge, including scissors. This is a mistake and can wind up being a costly mistake when you have to replace both your scissors and the knife sharpener. There are sharpening devices specifically designed to handle scissors. Or you can bring your scissors to a sharpening pro who will usually have the right equipment on hand to also sharpen scissors. Another thing to keep in mind about trying to use a sharpener to sharpen scissors is that by using the device in this fashion you are likely voiding the warranty. As such if you damage the device trying to sharpen scissors you’ll need to pay to have it repaired or replaced as the warranty won’t cover it. Also, certain types of high end scissors also come with a warranty. And, just as with the sharpener itself, if you try to sharpen them using a mechanical sharpener you can say goodbye to the warranty protection. The bottom line is to always use the appropriate tool for the job at hand. That way you’re assured of the best possible result and any warranty remains in effect.
Place an old coffee mug upside down so that the bottom of the mug is exposed to the air. In a pinch, a coffee mug can serve as a surprisingly effective sharpening tool if you don't have any fancy equipment. The ceramic material of a mug is a material coarse enough to get good results. Indeed, some honing rods even use ceramic material to keep a blade homed in between sharpenings.
Steeling helps maintain sharpness. This process realigns the edge, correcting for dulling causes such as a rolled edge. A sharpening steel is a type of hardened cylindrical rod used similarly to honing stones. For example, a butcher steel is a round file with the teeth running the long way, while a packer steel (used in the meat packer's industry) is a smooth, polished steel rod designed for straightening the turned edge of a knife, and is also useful for burnishing a newly finished edge. Because steels have a small diameter they exert high local pressure, and therefore affect the knife metal when used with very little force. They are intended for mild steel knives that are steeled several times a day, but are not well suited for today's tougher and harder blade steels. Diamond steels are now available that have an industrial diamond coating and can remove blade metal as well as straighten, therefore used correctly they can re-profile a knife instead of just honing.
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.
The Idahone stood out on a couple of fine details, too: Its ergonomic maple wood handle was more comfortable than the synthetic handles on the rest of the competitors, and its hanging ring is amply sized and sturdily made of steel. The other ceramic rods we tested had smaller hanging rings, plastic rings, or no hanging ring at all. Hanging a ceramic rod is a good idea, because the material is somewhat brittle and can chip or break if it gets jostled around in a drawer or utensil holder.
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 9-inch honing steel is the perfect length for most people. Just slightly larger than the typical chef’s knife and slicing knife (usually the longest knives in a set), this rod will not be too much for most people to handle. Unlike the 12 and 14-inch rods featured further up this list, this 9-inch rod should be very easy to confidently and safely control.
I really liked this whetstone! I had a Smith's pocket sharpener that could get my knife sharp enough for working around in the yard (I have an Opinel no.8). However, in doing a little research I found that the sharpener was only around 600 grit on the finest setting. So this BearMoo 1000/4000 grit looked like the perfect step up, and it turned out to be the perfect stone for me. The pictures are an accurate representation of what you get. The removable rubber base was helpful when switching from one side to the next, and it kept the stone from sliding around. The instructions say that the stone can work with either water or oil, but that water is preferred. It said to leave the stone soaking in water for five minutes, and the stone worked like a champ. I especially liked how the instructions gave you an approximate time of how long the stone takes to sharpen a knife -- it just helped give me an idea that it would take about 15-20 minutes on the 1000 grit side, and then another 10-15 minutes on the 4000 grit. Just turn on a TV show!
The ProntoPro 4643 easily took a top-quality Mac paring knife made of very hard forged Japanese steel from badly dulled to paper-slicing sharp. Initially the knife struggled to slice through the paper and ultimately tore out; after sharpening, it swept through like a razor. And the ProntoPro 4643 was able to sharpen the blade to within ⅜ inch from the handle—that’s excellent compared with many competitors. For each knife, the whole process took about 60 seconds, and the padded handle and level base offered a secure, stable, confidence-inspiring grip.
Be sure to note what kind of edge the ProntoPro 4643 puts on a knife. Chef’sChoice describes it as having “a lot of bite.” That’s accurate. It’s also a nice way of saying that the edge doesn’t end up polished to a fine point but comes out rather “toothy,” or microscopically serrated. This result isn’t a bad thing at all; it’s the sort of edge that most traditional European knives, including those of the highest quality, came with. Toothy edges perform sensationally if you are doing push- or pull-cuts—the sort where you move the knife tip away or toward you as you slice, and the sort most people do. Just be aware that, if you are used to chop-cutting (pushing the blade straight down through a food item), you may have a hard time if you sharpen with the ProntoPro 4643.
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.
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.
For someone who sharpens blades only occasionally, and knows that they will not need to grind out a chip in the edge of the blade, for instance, a combination stone will suffice. The size that one chooses depends mostly on a trade off between cost and speed. The bigger the stone, the faster one can work. The smaller stones work just as well, they just take a little more time.
This is a good size stone and has the two different grits needed for knife sharpening. No instructions were included, but there are many websites with written and video instructions, so this is not an issue for most people. A fair amount of dust is generated during the sharpening process, so protect the work surface and wash the knife after sharpening is completed.
1. Diamond Stones. I’ve used two, many years ago, to sharpen steel knives & found that the diamond coating wore away. They did work well at first, but then I was sharpening on the backing material. This puzzled me, because diamond is harder than steel, but have only recently read that the diamond particles are torn off the backing material because they stick to the softer steel. Diamond stones are recommended for sharpening ceramic knives only. This info about diamond stones & steel knives I got from an Edge-Pro article.
