An electric knife or electric carving knife is an electrical kitchen device used for slicing foods. An electric knife requires less physical effort than an ordinary knife and produces neater slices. The device consists of two serrated blades that are clipped together. When the appliance is switched on the blades continuously move sideways to provide the sawing action.
They are also sometimes used for other purposes, including sculpting polyurethane foam rubber[1][2], cutting wood, cutting metal, and other solid or semi-solid substances and materials. Electric knives can be corded or cordless.
