The traditional compass has a sharp point that can punch a hole in the paper when drawing shapes. Exlicon doesn't have a sharp point so it won't damage paper. The tool also prevents the circle's center from slipping when used to draw. Exlicon consists of a base, long/short ruler, and water drop-shaped ruler. Magnets connect the wings and base for drawing geometries. The tool can precisely and accurately draw ellipses, circles in over 50 dimensions, and over 100 different sizes of arcs.
