Using your Nella chef knife is easy. When slicing, place the knife on the ingredient and use the heel of the blade for tough items to get the most leverage. For everyday slicing, use the middle part of the blade. To keep your knife in top - shape, hand - wash it after each use with warm, soapy water and dry it immediately to prevent rust. Avoid putting it in the dishwasher as the high - pressure water and harsh detergents can damage the blade and handle. Store the knife in a knife block or a sheath to protect the blade and prevent accidents.
