A dull knife is inefficient and makes the process of preparing food longer. A sharp knife is what you want; however, how do you know if the knives you are using are sharp enough for optimum use.
Many experts agree on the following ways that determine the sharpness of a knife:
The Slicing Test
One of the ways to check the sharpness of a knife is by slicing round food that has a slick surface. Some examples include tomatoes, onions with its peel still attached and a green apple. A sharp knife will be able to cut into these food types easily without much pressure and it shouldn’t roll off the surface. Once you start using a sawing motion or use its tip to pierce the surface, it’s about time to sharpen it. If the sharpness is excellent, a knife is able to make clean cuts and maintain the integrity of the shape of the food you slice. Using the best knife sharpener, according to Total Knife Care, allows you to keep your knife sharp for a long time.
Paper Slicing
This is a simple sharpness test that most people try; if you can slice a piece of paper without much effort, and it doesn’t tear and catch, the knife you’re using is sharp enough. This test will also let you identify any damaged or dull parts of the edge. If you are unsatisfied with slicing ordinary paper, take this test to another level by cutting magazine or phone book paper, because these are difficult to catch with an edge. Try to slice through these; if you do so effortlessly, then your knife’s sharpness is good.
Shave Your Arm
This test is quite dangerous so proceed with caution; carefully try to shave your arm hair. A dull knife won’t be able to cut the hairs and will fold over them. A sharp knife will easily cut through the hairs in one go.
Try these tests if you’re unsure about the sharpness of your knife. If it passes the test, it is sharp enough for optimum use.
