The invention is directed in particular to the putter's blade the face of which is designed to maintain the ball in balance, after it has been critically positioned before impact, while the ball is rolling torward the target hole after such impact. To this end the blade face is formed with a longitudinal edge which is the normal ball striking component of the golf club being located above the center line of the ball in blade striking position capable on proper alignment with the ball of causing the latter to roll with minimal deviation toward its target. On the reverse side of the blade there is provided a secondary ball striking edge located below the center line of the ball.
