Horizontal hinging is where the toe of the club finishes up perpendicular to the plane line, or the club face is laying flat against the inclined plane, post impact - see the finishing swivel above.
Vertical hinging is where the club face is at a 90* angle across the plane line post impact - looking directly at the sky; and Angled Hinging is mid-way between the two, say at a 45* angle.
