The clever design of the XL Compass Tool allows you to cut 24 different sizes of circles. This compact multipurpose pottery tool allows you to cut or write circles from 1/2 inch to 12 inches in diameter. You only need two needle tools (or equivalent) to use the XL Compass Tool on a slab of clay. If you’re not building by hand on your workbench, the pointed tip, flat sides and rounded end come in handy for throwing on the dial.
