Shanks
Utilities
Everything on the Shanks tab that is not a shank builder: what you run before building a band to get the size right, and what you run after it exists to lighten it or mark it.
Setting the size
Before any shank exists there is a curve at the right size. Get this wrong and every measurement downstream is wrong with it.
Finishing the band
Two commands applied once the band exists.

Estimate Size
Cut by Ring Size
