Used to indicate club path. It will become obvious if your club is following down a straight path to the hole or running inside out or outside in.
STROKE GROOVER BLOCK
Designed for several diﬀerent exercises. When putting use the numbers on the top to make sure that your follow through is equal to or longer than your back stroke, preventing deceleration. It can also be used to control club path. Position the block in such a way that the toe of the putter just barely touches the block. Now take you normal stroke. This will begin to give you the feeling of being square at impact.
