Whether you are throwing clay on the wheel, hand building or sculpting, the pottery rib is a classic and essential tool. Because it acts as an extension of the potters own hand, we believe it should function well and be a joy to use. Shape 0 Polymer Ribs are our smallest Polymer Ribs and one of our best sellers. The traditional kidney-shape of these potters ribs is the most universally recognized clay tool. These little ribs can get into tight places and are good for detail work. The Red Very Soft is excellent for finishing rims. All of our Mudtools polymer pottery ribs are made of a unique flexible material that will not develop burrs or cracks under normal use. We've found that over time the rib becomes even more polished. Each polymer shape is available in a variety of hardness.

  • The Original Mudtools Workhorse (Throwing, Smoothing, Compressing): Shape 2 is the firstborn in the Mudtools family—remade from Michael Sherrill’s favorite old rib and designed to be a dependable, everyday workhorse for pottery wheel throwing, smoothing, and compressing clay.
  • Burnishes Over Time + Resists Burrs: Built from Mudtools’ unique polymer material engineered to resist wear and the formation of burrs. With normal studio use, the rib becomes naturally burnished—helping it glide even smoother as it breaks in.
  • Signature Polymer Flexibility: Crafted from Mudtools’ proprietary polymer blend, the Shape 2 is flexible, durable, and glides over clay without sticking or dragging—leaving behind a flawless finish every time.
  • Color-Coded Firmness Levels: Each color represents a different firmness: Red: Soft – gentle touch for fine adjustments; Yellow: Medium – ideal balance for everyday use; Green: Firm – for controlled shaping and compression; Blue: Extra-Firm – for structure and strength
  • Made in the USA by Mudtools: Designed by potter Michael Sherrill and trusted by ceramic artists worldwide. Built to last, easy to clean, and comfortable in the hand—every studio needs at least one.
