Best Knife Sharpener: Top Picks for 2023

A sharp knife is an essential tool in any kitchen, but over time, even the best knives can become dull. This is where a knife sharpener comes in. A knife sharpener is a device used to sharpen and maintain the edge of a knife, making it easier to cut through food. There are many different types of knife sharpeners available, including electric, manual, and sharpening stones.

When looking for the best knife sharpener, there are a few critical things to consider. First, you’ll want to decide on the type of sharpener that best suits your needs. Electric sharpeners are quick and easy to use, but they can be expensive and may not work well for certain types of knives. Manual sharpeners are affordable and versatile, but they require more skill and patience to use effectively. Sharpening stones are the most traditional option, and they offer the most control over the sharpening process, but they can be time-consuming and require more effort than other types of sharpeners.

Another important factor to consider is the grit of the sharpener. The grit refers to the coarseness of the sharpening surface and can range from very fine to very coarse. A finer grit is best for maintaining the edge of a knife, while a coarser grit is better for sharpening dull blades.

At our testing facility, we spent countless hours researching and testing various knife sharpeners to identify the best options on the market. In the following sections, we’ll share our top picks for the best knife sharpeners, as well as the features and benefits that make them stand out.
