Unfortunately, this sharpener is not meant for use with serrated blades, unlike some of the others on this list. Also unfortunate is the fact that I was unable to find any record of the angle degree to which it will sharpen a blade. However, consumers have been very happy with its performance and estimate the angle to be somewhere around 16 to 18 degrees.
The Work Sharp WSKTS-KT Knife sharpener is the only sharpener on the market, which can handle every knife in your home. This device uses flexible abrasive belts, which enables it to sharpen different types of knives, from straight blades, curved knives, filet knives, tanto knives, gut hooks and serrated knives. Regardless of the shape of the blade, this sharpener is ready.
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.
Good choice between the overly complicated and expensive sharpeners I have had and the dirt simple stones that depend on your own technique. This device gives you some settings options, but doesn't let you go crazy and ruin your knives. Takes about 20 secs per knife to restore a great edge. Earlier Amazon reviews were key to my buying decision and I now agree with their judgment. I think this sharpener will serve us for a long time.
If I thought that the 12-inch option of the Messermeister rod was a little longer than necessary you must be wondering why I would include this Winware rod which is only available in a 12-inch option and a 14-inch option. I stand by my opinions and will confidently say here that I would not select either of these rods on the sole basis of their extreme lengths. That being said, many other consumers have selected these sharpeners, despite (or maybe because of) their length and have reported being very satisfied with the results they have achieved.
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.
There are numerous types of stone sharpeners on the market. However, the Chosera 5,000 Grit Stone remains one of the best. This wet stone knife sharpener is an improvement on previous versions, allowing you to handle more blades. It uses magnesium as a binder. Since these stones don’t soak up water, you will have to sprinkle it with water regularly, during the sharpening process. Due to its hardness, it does not wear out easily, which adds to the overall durability.
If no metal is being removed from the edge of the blade, it’s considered honing. Whereas if metal is being removed from the blade edge this is considered sharpening. Certainly, even honing will result in some microscopic amounts of metal being removed from the blade edge but not enough to be visible to the human eye, so the above definition is basically a solid one.
A: For many years there was a heated debate around this topic with manufacturer’s stating flatly the notion their products actually damaged knives was absurd, and many professional chefs claiming not only was it not absurd, it was common for mechanical sharpeners to damage expensive cutlery. So who was right? To a certain extent they both were. The manufacturers were correct in asserting that if you followed the instructions to the letter there was little if any chance your knives would be damaged. However, in reality few people actually followed the instructions to the letter and when they veered from the recommended course the potential was there for damage.

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.
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.
A steel is the shorthand term for a steel rod used to straighten knife edges. Any decent knife set includes one, but few people know exactly what it does, much less how to properly use it. If you don’t have a steel, go buy one for about $20. Joe will show you how to use it to maintain a sharp edge. Don’t waste your money getting a diamond-coated surface. You don’t need it to know how to sharpen a knife.
You want sharpening stones that will be useful for the majority of your edges now, and that will remain useful as you expand both your tools and your sharpening toolkit in the future. Ending up with duplicate stones or ones that are no longer useful as you gain new knives or tools is a waste of money. The goal is to start with something that will stay with you as your needs develop.
As noted above, both Chef’sChoice and Cook’s Illustrated advocate using the Trizor XV to convert 20-degree knives to the arch-shaped 15-degree edge, so if you have European-style knives, you can still use this machine confidently. You can also use the final honing stage to “strop” serrated knives—helping to keep the teeth polished and aligned—but the Trizor XV cannot resharpen them.
Aesthetics – While it’s true that most people keep their sharpener, (even their expensive mechanical sharpeners) in the drawer until it’s time to use them you’ll still want to be aware of whether your sharpener fits into the overall aesthetic of your kitchen when you do take it out to use. While sharpener designs are fairly limited to be sure you typically have some control over the color and finish of the device as well as design factors like whether the device is boxy or rounded in appearance. With a stone sharpener or a stick however you pretty much get what you get.
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.
Our test of the Brød & Taylor turned a dull blade into one that effortlessly and cleanly sliced both tomatoes and paper. Due to the reputation of V-notch carbide sharpeners, however, I was concerned about the durability of the edge, so I did an additional test: I used the Brød & Taylor to sharpen my old pocketknife, which uses 440C steel, one of the earliest knife-worthy stainless alloys and one that more refined alloys have since surpassed. I then made 50 slices through a cardboard box, rehoned and repolished the knife (but did not resharpen it), and made 50 more slices. After all that, I was still able to slice a tomato and peel an apple without problem. That’s impressive: Cardboard is so tough on blade edges that knifesmiths use it as a kind of stress test.
Chefs and meat cutters frequently pause and “steel” their cutting edges. Steeling doesn’t sharpen an edge; it straightens it. That’s necessary because the thin edge actually bends or warps while you’re cutting. If you could see the edge under a microscope, it would look wavy, and it would feel dull while cutting. Steeling the knife straightens out all those waves to restore a straight, even cutting edge. So when your knife begins to seem dull, don’t sharpen it—steel it first. Every time you grab a knife for the first time to begin cutting, steel it before you even get started. But it’s important to do it right or you’ll just make the edge worse. And don’t act like one of the Iron Chefs on TV and do it all up in the air—you’ll eventually wind up in the ER. Rest the end of the steel on a cutting board and do your steeling the safer and more accurate way. It’s very important that you steel at an angle between 20 and 30 degrees. Photo 1 shows you how to figure that out.
