We've all been there. The cutting board is out and an old knife is in your hand. You try to cut into a perfectly ripe tomato, expecting to slice through its red flesh like butter, only to watch the skin sink inward because the blade is so dull and worn down. Do you admit defeat and keep pulverizing that poor tomato into oblivion with that useless knife of yours? Or do you have a knife sharpener on hand to save the day?

Sometimes you don't realize just how dull your knife is until you use a newly sharpened one and experience the pleasure of a razor-sharp edge again. Believe it or not, using a dull knife is more dangerous than using a sharp one. That's because you need to use more force when chopping with a dull knife. With a dull knife, it's easier for the blade to slip off of the food and into your flesh. Using a sharp knife isn't just a matter of convenience — it's actually safer and protects your hands from harm (via University of Rochester Medical Center). Having an efficient knife sharpener is the key to maintaining your blades and safely preparing food. 

The good news is there are lots of different features and models to choose from. From electric sharpeners that do most of the work for you to manual models that give you more tactile control, there's a knife sharpener for everyone regardless of your budget or level of experience.

Best electric knife sharpener

There's an old saying that still rings true and serves as a good reminder: "Work smarter, not harder." This tidbit of timeless wisdom can be applied to just about everything in life, including the way you sharpen your knives. Electric sharpeners are a smart way to easily and effortlessly keep your knives in great condition. All you have to do is flip a switch, hold the handle, and draw the knife back a few times while the electric sharpener does the rest. In a matter of seconds, your electric sharpener will gently grind and polish your blade back to its shining, razor-sharp glory.

Two different sharpening modes provide distinct stages, sharpening and honing your blade with optimal precision. A triple set of suction cups on the bottom of this knife sharpener help keep it balanced and stable on just about any surface. If you're looking for an easier way to keep up with maintenance, this electric knife sharpener is a dream come true.

Best diamond-edged manual knife sharpener

Why choose to use a manual knife sharpener over an electric model? The truth is that both styles have their advantages and drawbacks. On the one hand, an electric model is more effortless and thorough, but some models may be too aggressive for more delicate blades. On the other hand, manual models require a little more physical effort but offer you more tactile control. Ultimately, there are excellent models in both of these categories, so it's just a matter of choosing wisely based on your specific needs.

This Chef'sChoice manual sharpener uses diamond abrasives to sharpen and polish at a 15-degree or 20-degree angle. This particular model will also work on serrated knives, making it ideal for those of you who want one knife sharpener that can work for just about any style of knife in your kitchen. This manual knife sharpener is made in the United States, is very comfortable to operate and easy on the hands, and is small enough to conveniently fit anywhere in your kitchen.

Best whetstone knife sharpener

When Iron Chef Masaharu Morimoto recommends using a whetstone to sharpen your knives, you know you're getting good advice from a trusted source. Using a whetstone might feel intimidating, since the sharpening process isn't partially guided the way electric and manual models are. At the same time, learning to use a whetstone properly can reward you with an ultra-sharp edge and help keep your beloved knives in better condition since whetstones remove less material than other types of sharpeners (via Serious Eats). You can also rest easy knowing that acclaimed chef and cookbook author J. Kenji Lopez-Alt happens to recommend this particular King Deluxe whetstone.

According to MTC Kitchen, this medium grit whetstone is one of the most popular choices by chefs in Japan. Using this 1,000 grit whetstone is ideal for those of you who are looking for a single whetstone that can handle the job of sharpening your knife on a regular basis. Once you dive into the gratifying world of whetstones and see the clear difference in your blades, you'll never look back.

Best serrated knife sharpener

Serrated knives are an important part of every kitchen. With their saw-like teeth, serrated knives are great for slicing through crusty bread, the tough skin of a pineapple, or a roast. Since some knife sharpener models don't work on serrated blades, it's a good idea to select one that's compatible so that you can ensure that every knife in your kitchen is sharpened to perfection.

This PriorityChef sharpener works wonders on both straight and serrated knives with a diamond-coated course wheel and a ceramic-coated fine wheel. The ceramic-coated wheel will work wonders on your serrated knife. All you need to do is pull your serrated knife through the ceramic-coated wheel about ten times and you'll be pleasantly surprised when you see the impressive results.

Best ceramic knife sharpener

Ceramic knives require special attention because they need a sharpener that is uniquely designed for them (via Ceramic Cookware Hub). That's because the blades of a ceramic knife are made from zirconia, which is extremely hard. Due to zirconia's inherent hardness, sharpening the blades calls for a material component that's even harder: diamond.

This Shenzhen Knives electric sharpener has a diamond grinding wheel with course and fine grit levels that can sharpen both ceramic and stainless steel knives. This model comes equipped with a shaving cartridge to efficiently catch all of the particles from the sharpening process, which makes cleanup a breeze. Considering that the lifespan of the diamond wheel is about a year, extra diamond wheels for this model can be purchased to ensure longevity and continued use. With a universal knife slot for easy operation, a plug-in setup that provides a continuous stream of unwavering power, and raised sharpening slots to securely guide your knife, this model has everything you need to get started sharpening just about any ceramic knife on the market. After nearly 1,000 reviews that average out to four and a half stars, it's clear that there are plenty of happy customers who feel pleased with their purchase.

Best honing rod for knife sharpening

Most people probably picture a honing rod in their mind whenever the topic of knife sharpening comes up. And many may not realize that honing and sharpening a knife are actually two different processes that work to achieve the same goal: sharpening the edges of your blade. While sharpening actually shears off dull material from your knife, honing is more of a realignment process that levels out the edge. One of the best ways to do that effectively is by using a honing rod, which is a long piece of steel with a handle.

The Noble Home & Chef honing rod is chromium-plated to prevent rusting, dishwasher safe, and very affordable. One key safety feature that sets this model apart is the fact that its honing rod is magnetized to collect airborne metal shavings, which prevents particles from becoming airborne and causing harm by entering food or the respiratory system. It's also built to last and comes with three different handle designs for you to choose from, depending on your aesthetic preferences. At just under 15 inches long and only 12 ounces, this honing rod is small yet mighty and its sleek design is sure to add some style to any kitchen.

The Noble Home & Chef honing rod is available on Amazon for $25.
