A try square is a common measuring and marking tool used in woodworking, metalworking, and other trades. It is a simple but essential tool for checking and marking right angles.




A try square consists of a straight steel blade, usually around 6 to 12 inches long, and a handle or stock that is perpendicular to the blade. The blade and handle are joined at a right angle, forming an "L" shape. The handle is often made of wood or plastic, providing a comfortable grip for the user.

To use a try square, you place the blade against the edge or surface you want to check for squareness, ensuring that it is flush against both edges. By aligning the handle perpendicular to the surface, you can verify if the angle is exactly 90 degrees. If the surface is perfectly square, the handle will rest flat against it.

Try squares are primarily used to ensure the accuracy of right angles during various woodworking and metalworking tasks. They are commonly used for marking and checking square cuts, joinery, and layout work. For example, when making a square cut with a saw, a try square can be used to mark a line perpendicular to the edge before making the cut.

Try squares come in various sizes, with larger ones being used for larger projects and smaller ones for finer, more detailed work. They are often marked with measurement scales along the blade, allowing for quick measurements and layout work.

In summary, a try square is a simple but crucial tool used for checking and marking right angles in woodworking, metalworking, and other trades. It helps ensure accuracy and precision in various tasks that require squareness, making it a staple tool in the workshop.
