This unique hold stops wrist breakdown and gets the ball all the way to the hole.
There's nothing worse than leaving a birdie putt (any putt, really) short. It tends to happen when you swing up on the ball, catching it low on the face. But there's an easy fix: Extend both index fingers down the handle when you take your grip (top photo). Most players extend only the right index finger, which makes it easy to "flip" the putter at impact and catch the ball on the upswing. Make a finger match on both sides of the grip and you'll stabilize your stroke for an extra-pure roll.
