New rules to help golfers putt better

IN the last 20 to 30 years, the design of the golf putter's club head has undergone a radical change.

The putter was originally a forged iron piece very similar in shape to the current irons.

Through attempts to lower the centre of gravity of the club head, it evolved into a shorter, thicker head slightly curved from front to rear. The introduction of investment casting for club heads has allowed for drastically different shapes.
