A dull knife is a pain to use. You have to work harder than necessary and you make a bigger mess than you have to. Fortunately, there are countless knife-sharpening options on the market. But before you settle on a tool, ask yourself a few questions. Are you willing to learn the proper way to use a traditional sharpening stone, which puts a wicked edge on a blade but needs care and a bit of skill? Do you want the easiest, fastest way possible of walking away with a sharp-enough edge? Finally, do you want a device specifically for kitchen knives and other small tools, or a handy machine that can sharpen everything from a paring knife to long-handled pruners? There’s a lot to be said for the satisfaction of hand-sharpening a knife on a traditional whetstone. But there’s a lot of convenience in simply whipping out a paring knife, pulling it through an electric sharpener, and going to town on that pile of veggies on the counter. Here’s how to hone in on the perfect solution for you.
