15 Best Knife Sharpeners

We’ve all been there. Inspiration hits, and you run to the store for the ingredients to a delicious meal, coming into the kitchen excited and ready to begin cooking up something delectable for dinner. Within minutes, you are angrily hacking at a tomato, desperately trying to dice it neatly with a knife blade that is so dull it will barely get through the ripened skin. Your evening of gourmet adventure has been railroaded in the prep stages. Often we blame the knife and give up in frustration. Take heart kitchen warrior, there is another way!

Knives are crafted to be straightened using honing steel regularly, anywhere from every few weeks whenever used, depending on what you are cutting, and also sharpened a few times a year. So when was the last time you took a good look at your knife sharpener? If it was when you moved into your first place, it might be time to see what is out there in the world of knife sharpeners. While honing merely straightens the knife and removes small imperfections, a truly dull knife needs to have material removed from it by a sharpener. Many newer knife sharpeners on the market, and most of the industry leaders identified below, have both sharpening and honing functions in a single product. If it has been a while since your knife saw the inside of a sharpener, get your evening back on track with a few swipes through one of the knife sharpeners you can find below and dice your way to a delicious dinner.

What should you look for in a sharpener? First of all, you need to know what the sharpening market offers. There are three main types of sharpeners for the average home cook: electric, manual, and stones. Take into account your comfort with knife sharpening as electric sharpeners are easiest to use and range up to stones, which require some development of skill. All the products mentioned here have taken safety into account, featuring non-slip bottoms, special handles, and intelligent engineering to keep users as protected as possible.

 Sharpener features are also an important consideration. Some knives require sharpening at a certain angle to maintain factory quality. European and American knives are manufactured with a twenty-degree edge while Asian knives carry a sharper fifteen-degree angle. Some cooks prefer to adapt all knives to the sharper Asian setting for more precise cutting, while others prefer to maintain the original factory condition. Also, serrated knives require a particular sharpening, so if you are looking for an all-in-one tool for your kitchen, you need to pay attention to the capabilities of a potential sharpener. To address the comfort level of every home chef, we’re listing five sharpeners per type in a variety of price points are listed below.

Top 5 Electric Sharpeners

Electric knife sharpeners take all the guesswork out of the process of sharpening a knife. They are typically more expensive than the other types of sharpeners, but also include multiple settings, safeguards, and options to get knives to their ideal slicing state. However, they typically do sharpen to one pre-determined angle, so they may not be suitable in a kitchen where both Asian and European knives should be maintained as the factory sets them.

Top 5 Stone Sharpeners
