A very practical wood potter's rib featuring a broad, evenly curved arc and a long straight edge – the basic contours needed to control thrown clay forms. But what makes this tool unique are the notches at either end, one V-shaped, the other U-shaped. With the straight edge on the wheel head it's easy to impress a distinctive, contoured foot roll. 2 1/8" x 5 1/8" (5.4 cm x 27.7 cm)
