Cutting tools are tools used in machining for cutting operations. Most knives are machine, but also hand-held. Since tools used in machine manufacturing are basically used for cutting metal materials, the term "tool" is generally understood to mean a metal cutting tool. The cutting tools for cutting wood are called woodworking tools. The material from which the tool is made must have high hot hardness and wear resistance, the necessary flexural strength, impact toughness and chemical inertness, good manufacturability (machining, forging, heat treatment, etc.), and be not easily deformed. Generally, when the hardness of the material is high, the wear resistance is also high; when the bending strength is high, the impact toughness is also high. However, the higher the hardness of the material, the lower the flexural strength and impact toughness.
