The woodworkers try-square is composed of two main parts - the stock and the blade. The blade is made from hardened and tempered steel which makes is resistant to damage. The stock is usually made from rosewood although cheaper versions can be made from plastic or cheap woods.
A brass face is added to the stock to ensure a straight edge.
   

A typical use of a woodworkers try-square can be seen opposite.

The try-square is pushed against the straight edge of a piece of wood and a marking knife is then used to mark a straight line across the material. The line is continued all the way round the wood (all four sides are marked). This type of marking materials helps if a joint is to be cut or the end of the material is simply to be sawn away.

   

 

   

An alternative use of a try-square is to test the edge of a piece of wood to check how square it is (has it got a 90 degree angle along its length?). The try-square and material are held up to the light and the try-square is moved along the length of the wood. If light shines through any gaps between the blade and the wood, then the edge is not square.
