A good takeaway sets the pace for a good swing. Unfortunately, many amateurs get off to a shaky start: They lift the club and roll their hands away from their body, which draws the clubhead inside and opens the face. As a result, they make erratic contact.
To guard against such takeaway faults, pretend someone is holding a Samurai sword just above your wrists at address (below). You'll be forced to keep your hands low -- under the sword -- which keeps the clubhead in front of your hands, preventing a quick move to the inside.
Lift up too soon, and you cut yourself. Miss the sword, and you're on your way to solid ball-striking.
