Begin by sharpening the knife from the front side. Sharpening is completed when the knife has an even burr. Only use a flat-surfaced stone to finish the back surface of the blade. Sharpen the blade from the edge to the spine. Do not sharpen at too great an angle between the blade and the stone. The stone used to finish the cutting edge of the blade should contact the edge evenly.
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.
Unlike our Top Choice for this category, most rods are actually made only to hone your blade, not to sharpen it as well. To hone something means to straighten it. The very thin cutting edge of any blade will become warped over time. It will not be visible to the naked eye, but it will be warped. Tiny folds and grooves will find their way to your blade’s edge, making it seem as if it is growing dull. Using a honing rod, you can push those folds back into place and create a straighter, stronger, sharper blade. Of course, this will only work for so long, as your blade will eventually grow dull in other ways.

Works well. Just got it today, sharpened two pocket knives, one a 8Cr13MoV Chinese steel, the other s30v American steel The stone made short work of both steels (which were pretty sharp already). But notably was able to make the s30v hair shaving sharp easily, something I've had trouble with. Inexpensive and useful, I love this stone. It's not the Ninja sharp 8000+ grits that you can find, but for pocket knives and EDC, it's perfect and inexpensive. Get One!!!!!!!!!!!!
A: Like cars, knife sharpeners run the gamut from basic to luxury and like cars the price can vary from extremely affordable to more than some people might want to spend. You can get a high quality sharpener that will put your knives through a 2 or 3-stage process which will result in an incredibly sharp edge for less than $20. Or you can buy a mechanical sharpener that will produce a virtually flawless edge for $200+.
If you have already perused some of the knife review pages on this website, you have probably noticed that I usually select a “Best in Class”, “Best Value”, and Best something else for each Top Three Choices section. What I quickly noticed when working with these knife sharpeners was that it simply wouldn’t be possible to do such a thing. Each of these types of sharpeners is so different from the other types that I felt all deserved their very own “Best in Class” selections.
Do you have dull or blunt blades that are lying in the kitchen? If yes, then you can easily bring them back to life, with the Priority Chef Knife Sharpener. It doesn’t matter how long the knife has stayed without being used. This knife sharpener has all what it takes, to revive your knife and make it as sharp as new. You don’t need to spend money buying a new set of blades. With this device, you can recycle your dull, old and forgotten stockpile, and then sharpen them back to life.
But Joe has a quick, drop-dead simple approach that he’s been teaching to amateurs to learn how to sharpen a knife. You’ll only need a couple of inexpensive sharpening tools and a bit of practice. Master it and you’ll be amazed at how well your knives perform and how much more fun food prep, carving, slicing and peeling can be. Or at least how much less painful. Read on to learn how to sharpen a knife.
Hold your knife at approximately 20° in relation to the honing rod. Your angle doesn't need to be exact, just approximate. Whatever angle you decide to choose, or unwittingly end up choosing, make sure to maintain the same angle throughout the honing process. Changing the angle used during the honing process won't smooth out the metal in the blade as much as using a consistent angle will.
A nearly foolproof manual sharpener that looks like modern art, the angle that the knife is inserted into the sharpener determines how aggressive the sharpening is (yes, there is a correct angle for sharpening your knives). You can start by sharpening the knife then hone it to a fine finish in the same slot. If the knife doesn’t need sharpening, you can use this for honing only. This sharpener self-adjusts, and sharpens the knife edge to its original angle, so you don’t need to know the edge angle to sharpen the knife correctly, and there’s nothing to adjust. The tungsten carbide sharpeners will last a long time, but can be replaced when necessary.
Method 3: Use a Sharpening Stone. This is the best method by far. Not only will it give you the best edge, it also removes the least amount of material. With a fine enough grit, your knife should be able to take hairs off your arm when you've finished. Additionally—and I'm not kidding about the importance of this one—the act of sharpening your knife will help you create a much stronger bond with your blade, and a knife that is treated respectfully will behave much better for its owner. The only problem? It takes a little know-how.
4. Start sharpening the first side of the blade. With your blade set at the prefect angle, you’re ready to start sharpening. Imagine you’re carving off a slim piece of the stone’s surface. Personally, I bring the blade into the stone. Other people stroke the blade away from the stone. Both ways work, so just use whatever technique you prefer. If the knife blade is curved or if it’s longer than the stone, you’ll need to sweep the blade sideways as you work, so the entire edge is sharpened evenly. Apply moderate pressure as you sharpen. No need to bear down hard on the blade. After you make one stroke, start back at the beginning and repeat. Do this about 6-12 times.
The thumbnail test (not recommended for novices) - With this test you take your newly sharpened blade and run it oh-so-delicately over your thumbnail. If you feel it digging in even a tiny bit, it’s likely sharp enough. If on the other hand it just slips and slides across the surface of your nail it’s not sharp yet. Again, this test is only recommended for people with lots of experience handling knives and even then they’d probably be better off just grabbing a tomato or a piece of paper.
Cerax and Suehiro stones from Suehiro are a little harder, and as such do not wear down as quickly as the classic Japanese water stones. The 8000 grit stone will perhaps give you the best cutting edge with a mirror polish on chisels and similar blades. Suehiro also makes a small combination stone for those who do not sharpen tools all that often and are reluctant to spend extra for a Cerax stone.
Electric sharpeners use rotating ceramic or abrasive-impregnated metal wheels to grind a new edge into a blade. Low-end models, which start at about $25, feature a single set of coarse wheels that produce a rough, if potentially serviceable, edge—it depends on how even the edge is, and that’s a matter of overall design and engineering. Higher-end models can cost $200 or more (and professional models for slaughterhouses can approach $1,000), but they feature stronger motors and multiple grinding wheels—coarse, fine, and often polishing/honing—that when well-engineered can put an extremely keen, durable edge on knives of every style and quality.
If you have invested your hard-earned money in a quality set of kitchen knives it is important that you care for them properly. Of course, you could always send them away for sharpening, but why pay money to have someone else do what you could easily do yourself? Not to mention the inconvenience of having to drive them to and from the sharpener or pay shipping and handling to send them by mail.
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.

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.)
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.
Once the burr is removed, it's time to test the sharpness with paper. Hold a piece of newspaper at about 45°, with a bit of tension, and slash lightly with each point of the blade. If it cuts through easily, your knife's sharp. Warner speedily lacerated his newspaper, but I of course struggled. There is an element of technique involved, he reassured me.
