All of the Mudtools stainless steel ribs are all made of cutlery-grade stainless steel and have varying flexibility among the tool styles

SS0 Shape 0 is our smallest rib shape and one of our bestsellers. The traditional kidney shape of this potter's rib is the most universally recognized clay tool. This little rib can get into tight places and is good for detail work.

SS1 Shape 1 is a traditional kidney-shaped rib, probably the most universally recognized pottery tool. It fits well in the hand and is useful for sculpting, hand building and throwing clay. Shape 1 is not too big, not too small. It's just right. 

SS5  Shape 5 is the same traditional kidney shape as Shapes 0 and 1, only bigger. It offers more surface coverage, which makes them great for smoothing a slab of clay.

SS7 Here is a rib that stands firm. Made of a heavier grade stainless steel, the Shape 7 has less flexibility than some of the other ribs. The blunt end is good for carving away material or removing waste clay on the wheel.
