Soft Pottery Ribs, 3Pcs Rubber Rib Tool for Pottery, Silicone Pottery Clay Tools and Supplies, 3 Sizes Review (2026)

Who this three-piece set suits

This set targets someone assembling their first basic tool kit rather than a potter who already owns a wall of specialty ribs. Because all three ribs share the same soft silicone and simply scale up or down in size, it works as a low-commitment way to have a rib on hand for a mug-sized piece and a larger bowl or plate without buying three unrelated tools. Hand-builders smoothing coils and slabs will get more consistent use out of it than wheel throwers doing heavy compression, since the tools are described for carving clay shapes, polishing surfaces and erasing finger marks rather than pulling walls. It is a reasonable add-on for a starter kit or a classroom setting where a few soft ribs need to be shared across simple finishing tasks.

Material and the three sizes explained

All three ribs are made of the same silicone plastic, which is soft, flexible and will not crack the way a dried-out rubber rib can over time. The set includes a large rib, a medium rib and a small rib, each roughly rectangular with slightly different proportions rather than a kidney or oval shape. The large piece measures about 4.7 by 2.4 inches, the medium about 4.1 by 2 inches, and the small about 3.4 by 2.2 inches, so the size difference is moderate rather than dramatic. The total set weighs under 3 ounces, light enough to keep all three in a small tool roll or apron pocket. Because they share one softness level, the sizes are really about matching the tool to the piece rather than offering a range of firmness for different pressure levels.

Living with soft ribs day to day

In daily use, these ribs are meant to be rinsed clean with water and reused rather than treated as disposable, which keeps ongoing cost low once the set is bought. The soft silicone flexes against curved surfaces, which makes it forgiving for smoothing rounded forms but also means it will not hold a sharp edge the way a metal or hard plastic rib does when trimming a foot ring or cutting a crisp line. Because none of the three pieces is labeled with a specific firmness or durometer rating, it is hard to know in advance exactly how much resistance the rib will offer against wet clay compared with a named firmness system some other brands use. Expect to supplement the set with a firmer rib once trimming or wall-compression work becomes a regular part of the routine.

How it compares with named ribs in the guide

This set ranks seventh of eight in the site's pottery ribs guide, well behind tools like the Mudtools Shape 1 polymer rib and the Mudtools stainless steel Size 5 rib, both of which are sold as a single, purpose-built shape with a defined firmness rather than a generic three-pack. Xiem Tools' soft silicone clay rib sits in the same soft-silicone category as this set but scores higher, largely because it is marketed with a clearer single-purpose shape rather than three unlabeled sizes. The gap comes down to specificity: buyers who already know they want a kidney-shaped soft rib or a firm metal rib for trimming will likely get more precise results from those named tools than from this general-purpose three-pack.

Verdict and who should buy a different rib

Choose this KALIONE set if you want an inexpensive way to add three sizes of soft, reusable silicone ribs to a starter kit and your work is mostly smoothing rather than trimming or wall-pulling. It earns our score of 7.2 out of 10 for being a solid basic option that lacks the specialization of named competitors. Potters who need a specific firmness for wheel trimming should look at a firm metal rib like the Mudtools stainless steel option instead, and anyone who wants one dedicated shape rather than a mixed-size set will likely be happier with a single, purpose-built rib such as the Xiem Tools silicone rib.
