This tool was designed to train and develop "youngsters" and apprentices to lay out and check their work more efficiently. The combination square is far superior to clumsy, old-style solid workshop-grade squares that are still being used in some vocational schools and apprenticeship programs around the world. Tool is similar to our popular Combination Square Series, but is a more economical value. The combination square, as its name indicates, handles many jobs, saving the apprentice from buying more individual tools. This combination square can be used as a try square, 45 degree miter, a depth gauge, a height gauge, a layout tool, and as a rule.
