All of Mudtool's polymer ribs are made of unique flexible materials that are resistant to wear and the formation of burrs. 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.
