Detailed description of the square tool
The sizes of the squares ranges from two to eight centimetres. The frame that forms the square is one centimetre wide.
Two finger fitters are provided in opposing sides. Two opposite diagonal corners are rounded. The others are sharp. At each corner a pushpin marker is located.
Along the outside and inside a small indent is provided at every centimetre.
In case the length of the side is odd numbered, there is in addition an indent at the halfway position.
