Combination Try Square

A Combination Try Square is a versatile measuring tool used in woodworking and metalworking to ensure the accuracy of right angles and measure or check the squareness of edges and surfaces. It typically consists of a ruler or blade attached to a handle at a 90-degree angle, allowing for both linear measurements and the verification of perpendicular angles. The "combination" aspect often refers to additional features, such as a spirit level or an adjustable head, which enhances its functionality for various precision tasks.
