Product Information

Another longtime favorite of blade enthusiasts, the Spyderco Tri-Angle Sharpmaker has been around for decades. Its popularity stems from a combination of lightweight portability, ease of use, and effectiveness producing a razor-sharp edge.

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.Includes a diamond rod for sharpening serrations, a coarse carbide notch, and a ceramic finishing notch We did not expect a knife sharpener at this low of a price to work as well as it does, but the Longzon 4-in-1 really delivers. As the name suggests, the manual sharpener has four slots—three successively finer ones for standard knives and an extra-wide one especially for sharpening scissors and shears. Some manual sharpeners take a little practice to use correctly, but the Longzon's design and included directions make things simple. There's even a QR code link to video instructions if you're more of a visual learner. Design: We highlighted sharpeners that featured multiple stages for maximum efficiency or different slots for different blade sizes. Knife sharpeners can be bulky, so we also focused on compact sizes that you could store easily in your kitchen. To sharpen serrated knives and ceramic knives, look for a model that specifically states its suitability for these blades. Using a standard sharpener on a serrated or ceramic blade will drastically reduce the useful life of the knife. Material

All of the knife sharpeners we tested for this list were of the pull-through variety, which tends to be easier to use. A good sharpening stone is also highly effective for maintaining your blades, but there’s a steeper learning curve. How easy or difficult the sharpeners were to operate: We tested both manual and electric sharpeners, noting their learning curve and ease of control. We also appreciated the models that came with easy-to-follow directions and video instructions. 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). Place the heel of the blade (where it connects to the handle) against the steel, with the knifepoint angled slightly upwards. 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.

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. Work Sharp Electric Culinary E2 Kitchen Knife Sharpener: This sharpener is easy to use and has an excellent price for an electric model, but you get what you pay for. We found that it did just an OK job at sharpening, while its feet let it slide around on the countertop, which is a definite safety hazard. A brand-new knife has (in theory) a perfectly straight blade, ground down to a precise cutting edge at a specific angle. As you use it, the metal on the edge gets damaged on a microscopic level, causing uneven spots that can get caught on foods and create a ragged tear rather than a clean cut. A sharpener does for a metal knife basically the same thing that sandpaper does for a wooden board: It shaves off a layer of uneven material to make the surface smooth and even again. Different models of sharpener use different materials and methods to remove metal, along with different methods of holding the knife in the correct position while doing so. Consider the cut of the blades you’re interested in sharpening. Be sure that the sharpener you’re eyeing can accommodate those scissor blades or serrated knives, for example.
