While cheese knives are ideal for properly slicing and cutting cheese, the different types of cheese available to choose from necessitates a need for different types of cheese knives. A soft cheese requires a sharp knife and it is often best to choose one with serrated edges to ensure the blade doesn’t become stuck on the cheese. You will often find that knives for soft cheese will have holes in them, which helps to prevent sticking. A harder cheese will require a tougher and more robust blade.
