The best putters who use the iron club employ the wrists to a considerable extent, and let the head swing backward and forward like a pendulum. There is no doubt that this is a very effective method, especially on very true greens. The only objection that can be raised against it is that it requires great delicacy of touch.
The club is not pushed after the ball, as in the first case, but is swung by the action of the wrists; and you will find that the smallest predominance in the strength of the grip with either hand will cause the ball to reflect from its proper line. In order to preserve accuracy the shaft must be held equally firmly in either hand, and neither arm must be brought too much into the stroke.
There is, it seems to me, another objection on general principles to the use of the iron putter, and that is the difference already shown between the short approach and the put. You cannot blend the two as you would if you used a cleek to put with.
The best iron putter is probably the Park patent with the bent neck. It enables you to hit the ball rather more squarely, and does away in great measure with the tendency to let the ball glide off the surface.
