All of our polymer ribs are made of unique flexible materials that are resistant to wear and the formation of burrs. We've found that with general use these ribs become burnished over time. Each polymer rib shape is available in variations of flexibility. 

  Red -  Very Soft 

  Yellow - Soft

  Green - Medium

  Blue - Firm

Whether you are throwing clay on the wheel, hand building or sculpting, the pottery rib is a classic and essential tool. It acts as an extension of the potters hand to create shapes and surfaces that fingers alone can not achieve.

We believe our tools should not only function well, but should be pleasant to look at and a joy to use. Whatever you want to make, we've got you covered.

Shape 4 is also available in stainless steel.

These ribs are fantastic, and this is my all-time favourite shape they come in. I use the red rib all the time in throwing bowls, and often use the red or yellow ones when I am smoothing out slabs using the flat edge. The red is also useful for helping with finishing on clay bodies with a little grog, where sponging would bring out the rough texture. The size is perfect for my hands. I do also have a green rib in this shape, but I find the yellow is hard enough for the way I use ribs, so I don't reach for it often.
