Briefly describe the difference between the Pen tool and the Curvature tool

What will be an ideal response?

The Pen tool is meant for drawing precise paths using smooth and corner points.
With the Pen tool, you will edit direction handles to dictate the direction and
amount of the curve. You will also employ a host of other tools and keyboard
shortcuts to perform operations like converting anchor points, etc. The
Curvature tool is a "less demanding" tool than the Pen tool because it does not
force you to deal with direction lines like the Pen tool. This can be a little limiting
(to those of us used to the Pen tool), but it is meant to simplify path creation,
enabling you to create, edit, add/remove, and toggle between smooth and corner
points with the same tool.
