Here is Mustad's take on it.
http://www.mustad.no/www2010/products/hooks/hook-anatomyCommon Hook-Point Positions: The following categories are used to define the position of the point either
curved in towards the shank or away from the shank:

Hollow Point: This type,
like the needle point, is designed for fast penetration,
being hollowed or rounded out between the tip of the barb
and the tip of the point. The outer side of the point is
straight.

Beak Point: Sometimes called
a rolled-in point, this type has the point bent in toward
the shank of the hook. The rolled point is excellent for
baitfishing in saltwater. Besides being a description of
how the point looks like, Beak Point is also a registered
Mustad Trade Mark.
Curved-in Point:
There is no clear distinction between a Beak Point and
a Curved-in Point, in as much as a Beak Point is curved in.
But some specialists distinguish between them by saying that
the Curved-in Point differs from the Beak point in that the
entire spear is bent toward the hook shank. Although such
a point achieves a small bite, it is difficult for a fish
to disgorge.
