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.

  • Shape 1 is Mudtools’ best-selling pottery rib for a reason: it’s not too big and not too small, just right for a wide range of tasks. The classic kidney profile fits comfortably in hand and works equally well for wheel throwing, handbuilding, or sculpting, so it becomes the go‑to rib for daily studio use.
  • The medium‑size outline gives clear tactile feedback and steady control—ideal when you’re smoothing walls, refining curves, or bringing a piece toward its final form. It’s a practical bridge between very small detail ribs and larger shaping pottery tools, giving you a balanced, dependable feel for most projects.
  • Signature Polymer Flexibility: Crafted from Mudtools’ proprietary polymer blend, the Shape 1 Rib is flexible, durable, and glides over clay without sticking or dragging—leaving behind a flawless finish every time. Compared to wooden ribs, polymer ribs are much longer lasting.
  • Color-Coded Firmness Levels: Each color represents a different firmness: Pink – Ultra Soft; Red: Extra Soft – gentle touch for fine adjustments; Yellow: Soft – ideal balance for everyday use; Green: Medium – for controlled shaping and compression; Blue: 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.
