Slicing tomatoes is serious business, since they’re such a versatile food. A serrated knife is a knife with “teeth.” Since tomatoes have soft flesh, these knives ensure a clean cut without damaging the surface or shape of the tomato. Serrated vegetable knives are typically made of high-carbon stainless steel, though ceramic blades also exist. Some come with a sheath, which is handy to protect hands when the knife isn’t in use. Blades on these knives are typically four inches, though some are longer. Handles can be made of pakkawood (a type of plywood), rubberized or hard plastic, or aluminum. It’s a good idea to check the ergonomics and weight of a serrated tomato knife, particularly if you suffer from repetitive stress injuries or arthritis.
