Cutting lettuce with ceramic knife lessen rust?

Using a ceramic knife to cut lettuce will not affect the formation of rust, as ceramic knives are non-metallic and not prone to oxidization like some metal knives. Rust is specifically an iron oxide that results from the corrosion of ferrous metals when exposed to oxygen and moisture. Since ceramic knives are composed of materials such as zirconia, alumina, or a proprietary blend of ceramics, they do not contain iron and therefore cannot develop rust by interacting with lettuce or other food items.
