Shape 0 - small kidney · Smallest of the polymer rib shapes · Rounded oval with two edge radii · Detail work in tight areas · Green = medium flexibility · Polymer, no sharp metal edge · Hanging hole

Shape 0 is the one you reach for when the other ribs are simply too big - inside a narrow neck, down in the angle where a handle meets the wall, along the tight curve under a spout. Green sits in the middle of the five-level scale.
It is a rounded oval rather than a true kidney, and the two long edges are curved to different radii, so you get a tighter and a looser sweep out of one tool. Green sits in the middle of the five-level scale. If you are buying one grade to start with, this is the one that does the most jobs adequately. Polymer, so there is no metal edge to bruise the clay. Central hole for hanging.
