The Shape 1 Rib is Mudtools' bestseller. It's not too big and not too small. It's just right. You need one in your tool box, you really do. The traditional kidney-shaped rib is the most universally recognized pottery tool. It fits well in the hand and is useful for sculpting, hand building and throwing clay. 

All of Mudtools' polymer ribs are made of unique flexible materials that are resistant to wear and the formation of burrs, but with general use these ribs become burnished over time. This polymer rib shape is available in the following flexibility options: 

Red      -  Very Soft 
Yellow -  Soft
Green  -  Medium
Blue     -  Firm

Whether throwing clay on the wheel, hand-building or sculpting, the pottery rib is a classic and essential tool. It acts as an extension of the potter's hand to create shapes and surfaces that fingers alone can't achieve.
