Toughness

Toughness affects the durability of a knife. Hardness and toughness are opposites. A kitchen knife is structurally vulnerable to shocks applied from the side, and toughness is necessary to prevent breakage and spills. A knife with a good balance between sharpness and durability is an easy-to-use knife. To achieve both hardness and toughness, ingredients such as molybdenum and vanadium are added to the steel material.
