This triangle ruler is an answer to the constantly breaking corners of plastic set squares which most of us might remember from schooldays. Even when used with a cutter the edges won’t be damaged. The perforation of the sheet metal provides the transparency that is needed when drawing or cutting angles or parallel lines. The set square is made out of stainless steel with precisely etched lines and numbers.
