But don't be embarrassed! The correct way to hold a knife may not seem intuitive at first, but once you see how it improves mobility and efficiency, you'll find it hard to go back to your old habits. Here's how it goes: 1) Hold the knife handle in your hand with the blade facing up (sharp side facing you). 2) Now, close your hand around the handle and turn the blade down to face the table or your work surface (sharp side facing away from you). 3) Inch your grip up on the knife handle until your index and thumb just reach the metal part of the knife. 4) Curl your index finger slightly and rest your index knuckle on one side of the blade, with your thumb pushing against the other side of the blade. 5) Pinch the blade between your index knuckle and thumb, while continuing to hold the knife handle. When it comes to knife skills, your fingers stay still and your wrist is doing all the work. You're now holding the knife like a professional chef would! Let's chop an onion.
