What object does a sliding bevel primarily function with?

The sliding bevel is primarily designed for marking or measuring angles. It consists of a ruler and a pivoting arm that allows the user to set the angle to be marked. By adjusting the arm to the desired angle against the edge of a workpiece, the sliding bevel can then easily transfer that angle onto the material, making it invaluable for carpentry, metalworking, and other applications requiring precise angular measurements.

This tool is particularly useful in situations where accurate sharp angles are needed, such as when framing structures or laying out joints. The ability to quickly adjust and lock the angle allows for repeatable and consistent markings, which is fundamental in ensuring that pieces fit together properly. Other tools, such as levels or tape measures, serve different purposes and are not primarily oriented toward angle marking.
