What is the purpose of the cutting surfaces of a tool, known as a blade?

The cutting surfaces of a tool, known as a blade, are specifically designed to cut through various materials. This design usually involves sharp edges that can effectively penetrate the material, allowing for a clean and efficient cut. Blades are utilized in a broad range of tools, from knives and saws to scissors and chisels, highlighting their essential role in both construction and art.

The effectiveness of a blade's cutting action lies in its geometry and the material it's made from, enabling it to apply force in a manner that overcomes the resistance of the material being cut. This purpose is central to the functionality of tools in stagecraft and other hands-on trades, making it crucial for performing tasks such as shaping, trimming, or detailing different types of materials involved in production.
