The Medium Rectangle Shaped Rigid Metal Rib is a durable pottery shaping tool designed for creating clean, flat surfaces and sharp structural edges in clay work. Its rectangular profile makes it ideal for compressing slabs, straightening walls on wheel-thrown forms, and refining geometric shapes such as cylinders, boxes, and angular vessels. The rigid metal construction ensures strong control and consistent pressure without flexing, allowing for smooth surface finishing and precise edge definition. Perfect for ceramic artists, potters, and sculptors who need accuracy when shaping structured or architectural clay forms.
