An improved adjustable carpenters square is presented, which aids carpenters in marking and measuring work product to be cut or formed. The adjustable square can be set at a variety of angles to enable cut marking. It also possesses an attached measuring tape and a straight edge to combine three useful features in one tool, as well as a press-down tape stop to hold the tape in place. This invention can be used to scribe a line along a piece of material using the leading edge of the square as a guide instead of using the index finger of one hand, which often results in injury due to slivers from the material being scribed.
