Best Knife Sharpeners of 2019: Everything You Need to Know About Knife Sharpeners

The importance of knife sharpeners has become pertinent in recent years, especially in households. It isn’t something that only used by professionals chefs. Almost everyone uses them nowadays, and that’s why it is important to reinforce why they are so necessary from time to time.

Knife sharpening tools do more than just sharpening a knife blade. They make it more efficient, easy to use, and improve the longevity of the knife. Let’s look at the reasons that make knife sharpening tools essential and beneficial.

When a knife blade is sharp it is a lot easier to slice or chop the produce needed for cooking. A sharp blade allows you to cut cleanly without damaging your delicate goods like tomatoes, herbs, etc. When this happens, the food produce doesn’t remain or look fresh. A sharp knife is easier to use, the blade goes through very cleanly. With a blunt knife, you have to use a lot of brute force. If you cut a tomato with force, it is going to squish and your hands and you risk getting hurt. But neither of those things happens with a sharp knife.

Knife sharpeners are the best tools for sharpening your kitchen knives. And we are here to tell you everything you want to know about them.

Best Stone Knife Sharpeners

It won’t come as a surprise to many that there are certain kinds of stones that are used as knife sharpeners. These are commonly known as knife sharpening stones, whetstones or water stones. Stone knife sharpeners grind and hone the blade to make it fine and sharp.

Although knife sharpening stones come in different shapes, sizes and compositions, they are commonly differentiated by their grit. A larger grit stone tends to grind the blade and removes greater chunks. A finer grit is used for adding the finer, finishing touches to the blade and make it sharp and smooth.

Stone knife sharpeners come in natural as well as man-made forms. Artificial whetstones are more popular because the grit, density and material can be pre-decided for the stone to perform specific knife sharpening functions. It often accompanies some electric knife sharpeners for adding that final touch of finesse to a knife.
