Diamond Edge No.1 Knife Sharpener - Lifetime Use for Any Knife from Chef's, Utility to Steel Pocket Knives - Professional Safe Manual Knife Sharpening Tool

Product Information

A honing steel, sometimes also called a honing rod or a sharpening steel, doesn't exactly sharpen your knife. Instead, it realigns the cutting edge to smooth out microscopic bumps and jagged edges. The KitchenIQ Edge Grip manual knife sharpener has two sharpening slots with preset angles to make consistent, repetitive sharpening a breeze. The coarse side will reshape a damaged edge, while the fine side can handle regular smoothing of the rough edge as well as maintenance. This knife sharpener features a handle section to keep the user’s hand safe from the blades while also allowing a sure grip on the device.

According to Blake Hartley, Executive Chef at Lapeer Seafood Market, a sharpening steel removes material from your knife by moving the edge alongside the steel to restore the V-shape of a blunt edge. A honing steel is not used to sharpen but to restore the bent edge so that it's straight again.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.

Home chefs and knife collectors hoping to sharpen their valuable knives without breaking the bank should look into KitchenIQ’s Edge Grip 2-Stage Knife Sharpener. This compact pull-through sharpener features a budget-friendly price tag and a simple, guess-free sharpening system. This process is essentially the same with both a manual and electric sharpener, but the motorized abrasives in an electric model will do more of the work for you. The most important thing is to try to use the same amount of pressure and the same angle with each pull through the slot—different models of sharpener make this easier or harder, depending on their design. Unless the directions specify otherwise, it should take three to five pulls through the coarse slot, and then just a couple through each finer slot, to sharpen the knife. If it's not as sharp as you like, try a few more pulls through the finest grit slot, and if that doesn't work, try the whole process over again. While this mess-free system could work just fine on the kitchen counter, it takes up about 1 square foot of real estate. Storage is another consideration that should be factored in, since the unit is big and weighs almost 18 pounds with the base. The tool can be disassembled and stored in the box, but frequent users may prefer to create a dedicated workstation. After selecting the keyed holes in the base for our desired angle, we inserted the brown (coarse) stones for the first portion of sharpening and then finished up with the white (fine) stones. To sharpen a blade, we simply held it vertically as we drew it down and across the angled stones, alternating sides at each stroke. For most average blades, six to 10 strokes per side on each stone was adequate. Some of the especially dull blades needed extra strokes on the coarse stone. To finish the edge, we simply applied less pressure (almost none) while drawing against the white stones.

To discover the best knife sharpeners on the market, we collected an array of dull knives—plus several boxes of Band-Aids—and tested their performance slicing through paper, carrots, and tomatoes (and a baguette, for serrated blades), both before and after sharpening. We also measured each knife's sharpness scientifically, using an Edge-on-Up tool to record the exact amount of force needed to cut through a standard material. 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. The flexible belt helps accommodate knives of all different sizes, though we found that it also leaves a lot of wiggle room for the blade, making it somewhat difficult to keep knives at the exact correct angle through the entire sharpening process. The Easy Edge theoretically can sharpen a serrated knife, but it only sharpens the flat edge and not the serrations themselves, so we recommend against it. This knife sharpener is simple to use and sharpens very well, but with its high price, it's probably best for someone who spends a lot of time in the kitchen or is a professional chef. Rebecca Treon, who also updated this piece, is a food writer, experienced home cook, and mother of two. Her work has been featured in BBC Travel, Huffington Post, Hemispheres, and Thrillist.

This is another solid choice from Presto, improving the sharpness of smooth and serrated edges by about 60% each. We wish it left the tips of the knives sharper, though.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. Each knife sharpener will have its own specific directions, and you should always follow those, but in general, you insert the blade into the slot and pull it through with even pressure several times. It's important to make sure the full blade passes over the abrasive, all the way from heel to tip. Then, you repeat the process on the other side of the blade (though some sharpeners work on both sides at once), first using the coarsest slot and then each of the finer ones. 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. The Mueller cut through produce easily, for the most part, but its edge wasn't clean enough to finish off carrots without them splitting. We found it did a better job of sharpening the middle of the knives than the tips. It's also not compatible with serrated blades.

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 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. 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. 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. 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 sharpenersSharpening ceramic knives requires a more precise, delicate touch than sharpening stainless or high-carbon blades might. Shenzhen Knives’ Electric Diamond Knife Sharpener is up to the task with diamond grinding specially designed for ceramic blades. We did not love the plastic handle, however. It cheapened the feel and appearance a bit and did not match some of the other more substantial Wüsthof knife handles in our test group. Still, for pure function, we recommend this tool as one of the best.
