A pendulum, defined as a weight hanging freely from a pivot, experiences a restoring force from gravity that accelerates it downward toward the ball from its resting position.
-
Consequently, if the Blade putter strikes above the sweet spot, it forces the ball downward, compromising kinetic energy and preventing it from reaching the hole.
-
Likewise, hitting below the sweet spot causes the ball to jump, compromising kinetic energy and resulting in a shortfall toward the hole.
The Pendulum Swing S.A. Putter is meticulously crafted to eliminate these issues, ensuring a consistent impact on the golf ball with ample energy to roll toward the hole. Its advantage over a Blade putter lies in the geometry design featuring a full-radius putter face and a rear made of heavy-weight brass. This full-radius design is rooted in the physics theory of billiard ball collisions.

In billiards, where collisions between balls closely resemble those between the golf ball and the full-radius putter face, nearly elastic collisions occur, preserving kinetic energy. This conservation of kinetic energy is critical for a successful putt. The simplified illustration below combines the fact of elastic collisions with the assumption that momentum is always conserved. This collision eliminates ball dubbing or jumping, ensuring no resistance and loss of kinetic energy.
The illustration assumes equal mass for balls A and B, with B initially at rest. After impact, the initial velocity of ball A causes ball B to move forward without resistance, rolling at the same velocity. Similarly, the Pendulum Swing S.A. putter undergoes the same event, preserving its kinetic energy without compromise.

The principle of radius face putter design is within the USGA guidelines and with novelty that a provisional patent has been filed to the USPTO.
An innovative golf putter design called the Pendulum Swing S.A. putter. Crafted with three-piece components, this putter is meticulously designed to achieve impeccable balance, facilitating golfers in executing a flawless pendulum swing while putting on the green—the crucial aspect of the game.
In golf, putting holds paramount importance, as a poor putt can nullify all prior efforts made from the tee box or fairway. For many recreational golfers seeking an advantage to enhance their putting skills, the Pendulum Swing S.A. putter offers a promising solution.
Traditionally, putters are fashioned with a flat face, commonly known as a blade putter. However, recreational golfers often struggle to master the ideal pendulum swing with this design, leading to a decline in their putting performance. A prevalent issue among such golfers is falling short of the hole during putts.


The science behind putting with a blade putter emphasizes that the flat surface should make contact with the golf ball’s sweet spot, generating sufficient impact force to ensure a perfect roll toward the hole. Failure to strike the sweet spot, either above or below it, results in a loss of kinetic energy, causing the ball to fall short of the hole—an issue illustrated for clarity.
