FLORENTINEING is a surface finish, achieved by using a special
graver, which has a number of parallel grooves cut in
the bottom. The effect of this is that the graver
cuts many parallel lines at once. In Florentineing,
first a series of parallel cuts are made followed by a
second set, which are cut across the first set, at 45
degrees to the first set. The tool may be referred to
as a florentineing tool, or a line graver.
