I had reviewed 'Confessions of the grip: Are you secure?' video from KFC Crispy Members Only section. What I had realized over the years, based on an unsolicited tip I received in my early golf life was to place my trail thumb relaxed over the grip of the club. "Your thumb has no bearing in your grip."as I was told. This does not keep my thumb/index finger creases closed resulting in a poor grip. According to Tom's teachings in the grip is to keep those creases closed. I immediately grabbed a club and swung it with the corrected grip. It felt weird as changes from old bad habits do but for the first time, I can feel the club and my arms as one unit. I made several swings. Could this be my power leak? Undesired ball flight trajectory? What else?
How about painful calluses? Yes...they hurt. Are you suppose to have calluses? This is a result of a moving club handle in my fingers everytime I swing a club..At times it is unnoticed other than feedback from a struck ball. Sometimes I have to use medical tape over my fingers to be comfortable with holding the club because they would be painful. This did not occur overnight. Nor during my Sagutogolf training. This is years of taking on poor unsolicited advice which became an unnoticed bad habit for me in my swing. Allow me to share pics of my index fingers....
Right (Trail) hand...If you look closely to my thumb, there is a minor broken callus resembling a cut which is an indicator of my thumb location on the grip.
Left (Lead) hand which I always don a glove...
Anyone else experience this? Calluses are formed through friction which means my club was not secured in my grip in my entire golfing life. Tom, this is not normal, correct?
I use an interlocking grip.
@johnpfistnerjr - Correct - a properly secured grip will not tear up your fingers. You just commented on the grip in less detail in a different thread. I'll paste my same reply here:
Hogan talked about keeping the trail forefinger and thumb glued together while taking his grip, keeping the crease intact and ensuring there was no gap. Gaps = unsecure connection. Also, be certain that each thumb rests slightly to the opposite side of 12:00 on the handle - left side for the right thumb and vice versa for the left; neither thumb should be directly on top of the handle.
There are a couple of pages dedicated to the grip in Setup chapter of the S&T book. They don't advocate a specific type of grip, but there are certain baseline non-negotiables for a good that they do mention.
