RIB
Ribs are ceramic tools made of plastic, wood, metal and rubber and are used to smooth clay while turning with a wheel. They have this name because originally animal bones were used to make them. There are several sizes and two types ridged and flexible.
In English they are also known as kidneys
as some have the shape of a human kidney. In Spanish and Catalan the word tongue is used in both languages; in Spanish lengueta and in Catalan llengüeta.
