When you use the tool to adjust the spacing, you can use the knob on the tool to lock the spacing so that you can achieve precise measurement and drawing. With a maximum distance of 210mm between the two feet of the compass tool, you can accurately cut, draw lines and depict most items. This tool is a professional and accurate circular planner for geometric drawing, precise measurements, woodworking and leatherworking. The compass does not have a pen.
