Which tool is specifically designed for cutting through various thicknesses of cardboard?

The utility knife is specifically designed for cutting through various thicknesses of cardboard due to its sharp, retractable blade that can easily slice through materials like paper, cardboard, and thin plastic. Its design allows for precision and control, making it ideal for creating clean cuts without causing damage to the surrounding material.

Utility knives are versatile tools commonly used in technical theatre for tasks such as cutting scenic elements, crafting props, or working with costumes where precise cuts are needed. The blade can be replaced or extended when it becomes dull, maintaining its effectiveness over continuous use.

Other saws listed, such as a hack saw, crosscut saw, and back saw, are generally intended for cutting harder materials such as wood or metal. They may not provide the same level of finesse or safety for cutting cardboard, which can easily tear or become damaged if not cut with the right type of tool.
