Think about the last time you cut up an onion. How easy was it? Did your chef’s knife slice through the skin with ease? Was there minimal need for you to hold the onion in place? Or did you have to work the knife over the onion several times to cut it into your desired cubes or slices? Whether it’s veggies, fruits or mean, if you’re constantly struggling to slice, dice and chop, it’s time time to sharpen your kitchen knives.
While you might think you need to go straight to the store for a new cutting tool, we’re here to tell you that there’s still life left in your old, blunt knives. Rather than chucking out the old and bringing in the new, try a knife sharpener to solve your kitchen problems.
Knife sharpeners range from simple, one-step devices to more complicated, multi-stage options. The right choice for you will depend on your needs, and the number of knives you need to sharpen.
Regardless, the process of sharpening your knives from their blunted form will make a huge difference in your cooking routine. But, there are several different types of sharpeners that require different sharpening methods.
- Whetstone – Like sandpaper for your knives, most whetstones are designed to be used wet. To sharpen a knife, drag both sides across the course side of the stone a few times. Then, flip the stone over and repeat on the fine side.
- Built-for-Purpose Knife Sharpener – Safer for sharpening than whetstones and easier to use, built-for-purpose knife sharpeners usually feature hidden sharpening wheels or rods. All you have to do is drag your knife through the insert a couple of times to sharpen it on one or both sides.
- Honing Steel – A honing steel is not technically a knife sharpener. It’s a rod used to keep a knife’s blade straight. This process should be done weekly. Simply hold the handle in one hand and place the other end against your work surface. With your other hand, hold the knife and place the thicker part of the blade against the top of the honing steel. Push the blade down and pull the handle toward you until you get to the tip. Repeat on the other side of the blade.
- File – Knives aren’t the only blades that need to be sharpened. You likely have garden tools, fishing gear and parts of your DIY kit that could use sharpening. For these heavier-duty knives and blades, a file can be used. Just work the file over the blade to sharpen. Just don’t use a file on your kitchen knives as it tends to take off too much of the blade, shortening the lifespan of thinner metals.
Furthermore, having a sharpener at hand is always a good idea as well, especially for special carving occasions like Thanksgiving and Christmas. A quick pass through the sharpener will ensure your knives are razor sharp and capable of creating the uniform slices everyone loves to see on their plate.
Below, we’ve put together the 17 best knife sharpeners available online. There are options that take a few seconds to sharpen your knives as well as others which deliver a more comprehensive sharpening. There are also options that can be used to sharpen other tools around the home, like gardening tools and fishing gear.
Stop trying to cut through your food with a blunt blade, and enjoy the ease razor-sharp knives can bring.
