This is a tool that I use to trim the foot of my cups, bowls or any pot you can think of that has a foot.  I developed this so that I could create a decorative pedastal foot. On one side you have two 3/16in beads and the other end has three 3/16in beads. The tool dimension is 8in long x 1in wide and 1/4in thick. These are hand made and finished maple but wood variety is subject to change.
