From Garrity:
The scooped end of our Thumb tool allows you to use it instead of your actual thumb when hand-building. Pressing seams, shaping slabs, or even trimming a clay pot on the wheel, this pottery tool makes light work of any ceramic project.

size: 7″ long x 1.25″ wide
material: maple wood

Comfortable, beautiful, and practical.
