Fascinating IP of the Week – A Forged Advanced Perimeter Weighted Iron With Resilient Weight Insert

I just came across a fascinating patent directed to a forged perimeter weighted iron with a weighting means filling the recess in the back of the iron. The weighting means fills the recess and is substantially flush with the back face of the club.

The weighting means is really unique. It is composed of a natural or synthetic rubber matrix loaded with a heavy filler or particulate material such as lead. Not only does the weighting means allow for precise controlled club head weighting but it also reduces shock and vibration at impact. Even better, the weighting means can be preferably engineered to place more weight toward the toe or the heel to help shape the ball flight.

Cool, right? Pretty advanced thinking. Can’t wait to try out the demo clubs at the range?

Well, now for the rest of the story… The irons that I just described are disclosed in USPN 2,846,228, which issued in 1958. Pretty amazing! Check out the patent.
