The Interlocking Grip
The Interlocking Grip is a popular grip used by many players with smaller hands that want the control and feel of having both hands physically connect throughout the swing.
The pointer finger of the left hand and the pinky finger of the right hand are locked together and both fingers are resting off the club. The rest of the fingers are on the club like the other grips. (Demonstrated Below)
Note: All 3 of the middle knuckles on the right hand are in a diagonal line with the pointer finger's middle knuckle of the left hand. (Demonstrated by the Red line above)
