Shape 1 is Mudtools’ bestseller 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.
