A stub tip is cut straight across the top
and is the easiest to use since it has somewhat rounded edges
and corners. The tip is often held at a 90 degree angle to the
writing line. The line variation between down and cross strokes
will not be as distinctive as with the italics simply because
of the roundness. But it is not as position-sensitive as an
italic or oblique and so is generally more comfortable to use,
especially for someone new to customized nibs.
