Putting Problems? Perhaps This “Do-Drop” Putter is the Answer

This week a putter patent caught my eye just from the title alone. The patent is USPN 7048643 and the title is “Do-Drop Golf Putter.” Where in the world did that name come from! Check out this design keeping in mind that the handle is free to rotate:

The patent describes the invention as:

A golf putter having a bent shaft and designed to be used with an individual facing the intended travel direction of the launched golf ball. The golf putter comprises a bent shaft configuration, an upper handle assembly having a rotating upper grip, a fixed lower grip, and a putter head assembly. In operation, the right-handed individual will hold the golf putter with the left hand grasping the rotating handle assembly and the right hand grasping the lower fixed grip. The left hand and the rotating upper grip are held against the abdomen for stability purposes. Using the right hand, the individual rotates the shaft rearward and then forward to make contact between the putter head and the golf ball. The present invention golf putter comprises unique symmetry allowing a left-handed individual to use the golf putter simply by reversing the hand positions described. By enabling the individual to face the cup, the proposed invention provides better sight alignment and enables a more natural swing. The present invention shaft configuration and the rotating grip assembly function to allow the putter head to operate in a smooth pendulum motion to trace a smooth arc around the upper rotating grip as it is held firmly against the individual’s abdomen. This smooth pendulum motion in combination with the stability created by the proper positioning of the upper rotating grip, provide improved consistency and improved accuracy in putting.

I don’t think we will be seeing this one on tour anytime soon.
