The smart design of Garrity's new Compass Tool allows you to cut 14 different sizes of circles. With this compact multi-functional tool, you can cut or scribe circles ranging from 1 inch to 7 inches in diameter. You just need two needle tools (or any equivalent) to use the Compass Tool on a slab of clay. When you’re not hand-building on your bench, the pointed tip, flat sides, and rounded end come in handy while throwing on the wheel. size: 4.75” x 1.125”material: maple wood Comfortable, beautiful, and practical.Handmade by Garrity's creative team in St. Louis, MO.
