The Mudtools Edgy Rib is a precision tool for potters who care about clean rims, smooth forms, and consistent results. While it was designed for refining rims, its multi-edged design makes it one of the most versatile ribs in any artist's toolkit. Each side of the Edgy Rib offers a different contour—perfect for smoothing thrown walls, compressing bases, shaping curves, or detailing hand-built pieces. Its edges make it easy to reach tight spots and refine subtle transitions between surfaces. Made from Mudtools' legendary flexible polymer, it glides smoothly without sticking or marring your work. Available in four color-coded firmness levels, the Edgy Rib adapts to every clay body and working style—from soft porcelain to heavily grogged stoneware. Whether you're perfecting a rim or defining the character of a pot, the Edgy Rib is built to help your hands translate precision into art.
