It's an new grip that is extremely effective at keeping the hands square through impact. It's the result of a couple of years of research and testing.
What it does is create a slight clockwise force with one hand and a slight counter-clockwise force with the other hand thereby insuring that the club face stays square through impact.
The straight lock grip was developed for those golfers that have a habit of trying to "hit" with their bottom hands which generally results in a closed club face and a hook. It is very, very good at eliminating hand caused hooks. We have been quite pleased to see that most all golfers are just plain hitting the ball straighter and even a bit longer with the Straight Lock Grip.
The regular Power Thumb grip still works great. You don't have to have the Straight Lock Grip. It may help if you especially if you have any problems hooking with the Powerthumb grip.
