Here is a hefty round rib that will be great for your bowl work and it even has some pizazz!
I'm a woodworker and a potter, too. Deep in my potters soul I love combining beauty with function, with my need for something just a little different than I could get from the catalogs, I started making my own pottery tools. Here I can share my special tools with you.
About 4" across and 3/4" thick.
