We then sharpen the knife with its dedicated knife sharpener according to the manufacturers' instructions.

Place the heel of the blade (where it connects to the handle) against the steel, with the knifepoint angled slightly upwards. The EverSharp sharpened very effectively, leaving one blade 80% sharper than we found it. But, it also left scratches down the slides of the blades. If this doesn’t bother you, the Presto EverSharp may be worth a closer look. It feels sturdy enough to last a while. A good knife sharpener helps keep your favorite chef’s knife performing at its best. Those crisp, clean, precise cuts we all love from a brand-new knife won’t last forever — not unless the blade is properly maintained. Sharp knives are much safer to work with, too. Dull knives require more force to use, which increases the risk of slipping and catching a finger instead of slicing cleanly through that pesky onion. Carrie Honaker, who updated this roundup, is a food writer who has wielded many knives over the years. As a restaurateur and avid home cook, she knows the importance of caring for your knives to maintain steady, sharp edges. Her work has appeared in many publications, including Bon Appetit, Allrecipes, and Wine Enthusiast.Choosing a manual or electric sharpener depends on personal preference and budget. Higher-end electric sharpeners can be pricey, while cost-effective manual sharpeners can produce excellent results. Consider how likely you are to use the sharpener, and don’t be afraid to spring for a more costly model if it means you’re more likely to maintain your knives! Keep knives in a covered, safe environment when not in use," says Hartley. "Do a weekly light hone with steel or stone, always wiping away particles with a clean dry towel. Don't feel like you have to work fast—with a process like this, form is everything. Work out the proper form first, and then the speed will come." Can you sharpen kitchen shears with a knife sharpener? Electric knife sharpeners are typically the fastest way to put an accurate grind on a knife’s edge. Designed to sit on a countertop, electric knife sharpeners feature a succession of grinding wheels and angled grooves through which the user pulls the knife. The knife becomes sharper as it works its way through the stages. Pull the knife blade along the sharpening steel towards you, with enough gentle force that you can hear a grinding noise. A honing steel is a long rod, often included in knife sets, along which you run both sides of the blade before you start slicing and dicing. It helps maintain the integrity of the blade, straightening out some of the microscopically uneven spots on the edge without actually removing any metal. Used regularly—as in every few times you use the knife—it can help stave off dullness, but you'll still need to sharpen your knife on occasion.

We really liked the fast-working design of the Work Sharp knife and tool sharpener. It operated more quietly and efficiently than other electric models. With only four to six strokes per side on progressively finer-grit belts, we completely renewed a damaged and dull chef’s knife in about 5 minutes. The finest grit belt honed the edge to a mirrorlike finish. How sharp the knives turned out: We analyzed sharpness using a scientific tool called the Edge-on-Up, which measures the force needed to cut a standard reference material. When the sharpener has more than one setting, the coarse setting is the sharpener and the fine one is normally similar to a honing steel. Effectiveness: The Edge-on-Up tool helped give us an idea of each sharpener's efficiency, but we also tested our knives immediately before and after sharpening to gauge any noticeable differences.Before buying a knife sharpener, bone up on the difference between sharpening and honing as well as various key factors and features—including material, suitability, and safety—of these precision tools. Sharpening vs. Honing It doesn’t matter which knives you buy—they'll all need to be sharpened periodically. Besides making it easier to cut and chop, keeping knives sharp is also safer for your fingers: Dull knives can drag or skip while cutting, which can increase your chance of injury. How often you need to use a knife sharpener depends on exactly how often you use the knife, what you cut, and what surface you cut on, but professionals typically recommend sharpening once or twice a year. Brod & Taylor Professional Knife Sharpener: It looks like a piece of contemporary sculpture, and its maker claims that its spring-loaded design is foolproof to use, but we had to manually hold the unit open to insert the knife and weren't able to get very good sharpening results at all. Add a hefty price tag, and you've got a sharpener we wouldn't recommend. Though electric knife sharpeners are easy to use and relatively foolproof, they tend to be pricey and don’t provide any grind-angle flexibility. They’re not as compact as manual sharpeners, but most are relatively small enough to be stored in a kitchen drawer. What to Consider When Choosing the Best Knife Sharpener

Finish with a honing steel for best results. Rinse and dry the knife. You may also need to clean up the area around the whetstone. We rate each knife sharpener on how easy it is to set up and use, plus how easy the instructions are to follow. Things we learnt testing knife sharpeners The Wüsthof Easy Edge Electric Sharpener edged out the competition thanks to its effectiveness and ease of use. It is capable of standing up to professional environments as well as home kitchens. For sharpening on a budget, the Longzon 4-in-1 Knife Sharpener offers an impressive price-to-performance ratio.

Perfect Gift

We especially liked that the depth gauge and stopper pin allowed us to position a knife in the clamp exactly the same way every time. Also, because the double-sided stones simply slide down onto the rods, changing grits was fast and easy. Starting with the 100-grit stone, we reprofiled our blade to 20 degrees with just 10 strokes per side. We then progressed through the 200-, 400-, 600-, 800-, and 1,000-grit stones at four to five strokes per side before honing with the 4,000- and 8,000-grit strops. Actual sharpening time was about 10 minutes. German company Wüsthof has been making world-famous knives for more than 200 years, so it makes sense that its sharpening tools are also high-quality. The Easy Edge features a spinning belt that runs at three separate speeds for coarse honing up to final polishing, along with a one-touch program with indicator lights for each stage. An integrated suction fan also keeps dust out of the way.

We are not professional knife sharpeners, which should lend some confidence to readers who may not feel confident about learning on these tools. We simply followed the manufacturer’s instructions to sharpen at least four knives with each tool. We recorded any noticeable points on the ease of assembling and operating the sharpeners, their effectiveness and speed of sharpening the different knives, and then tested each blade’s sharpness. Jason Horn, a commerce writer for The Spruce Eats, updated this roundup to include data from our extensive tests of 22 sharpeners—10 electric and 12 manual—by both freelance testers and in our Lab in Birmingham, Alabama. The sharpeners we’ve recommended here all come with clear instructions and were praised by testers for their ease of use. That said, don’t be discouraged if it takes a moment or two to determine which angle and pressure to apply to best sharpen each blade. When working with sharp blades, safety is a top priority. Some sharpening methods, such as electric and pull-through countertop models, are inherently safer options. They typically have a nonslip bottom that helps keep the tool in place while sharpening a knife. This model is also magnetized to attract metal fibers during use, ensuring that the blade is sharp and ready for use right away. The loop on the bottom of the handle affords a convenient way to keep the Wüsthof on hand and nearby in the kitchen.The most versatile sharpeners can accommodate knife blades of different lengths and widths, and generally will offer more than one type of grit to ensure a smooth, even edge. Much faster and simpler to use than a whetstone, V-notch sharpeners have hardened materials (typically ceramic or carbide) installed in a preset V-shape that’s set into a notch in plastic housing. The knife is dragged from heel to tip through the notch, allowing the sharpening material to remove metal until the knife conforms to its preset angle (also known as the grind). If your sharpener has more than one setting, select 'coarse' for very blunt knives. The fine or honing setting is for everyday knife maintenance.
