I seem to have struck a nerve somehow by answering the original question, which was what formulas do you use to get parallel heels. The traditional triangular heel works well for many cuts. However, if you need to lean the graver over much to sculpt the edge of a leaf with a graver that has a short heel, a parallel heel avoids issues. Do you need to be exact, no, but being close helps limit issues.
