Sometimes you need to make a point! The corner point on the Shape 4 Polymer Ribs gives a beautiful line on the clay; you also get two flat surfaces and three radiuses. Michael Sherrill (creator of Mudtools) wants this one in his toolbox if he’s stranded on a deserted island.
All Mudtools polymer pottery ribs are made of a unique flexible material that will not develop burrs or cracks under normal use. We’ve found that over time the rib becomes even more polished. Each polymer shape is available in a variety of hardness.
