Mudtools Pottery Ribs – Shape 1 Polymer Rib (Red Very Soft), Kidney-Shaped Clay Shaping Tool (R1)

The Mudtools Shape 1 Rib is the all‑around workhorse you keep within reach from first shaping through finishing. Its medium, kidney‑style body hits the sweet spot for most hands and most clay projects—large enough to cover meaningful surface area, small enough to maneuver around tight curves and edges. That balance is what makes Shape 1 a perennial bestseller and a backbone tool for throwing, handbuilding, or sculpting. Built from Mudtools’ flexible polymer, Shape 1 flexes just enough to follow a form cleanly without losing control. It glides smoothly over clay, resists sticking or dragging, and tends to become burnished rather than worn over time, giving you a consistently refined finish session after session. Use it to smooth walls, refine rims, tidy transitions, or remove small irregularities as you move toward the final shape. Available in five color‑coded firmness levels—Very Soft, Soft, Medium, and Firm—so you can choose the feedback you want for your clay body, technique, or personal feel. Whether you’re working in porcelain, stoneware, or earthenware, Shape 1 delivers dependable, comfortable control for foundational shaping and everyday studio work.

• 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.
