Two of the worst causes of missed putts are WOBBLE and TWIST, and both are cured with Symmetric Technology. There is nothing new about the principle of polar symmetry, it was discovered by Sir Newton back in the 1600's. This principle of physics is not well understood by most people, definitely not understood by the designers of Blade and Mallet Putters.
Twist Test -- Hold the golf putter losely with one hand as shown, and then tap the location on the impact face where the ball is usually impacted. If the putter head twists upon such tapping, it suffers polar asymmetry and will always twist open when impacting the ball -- that of course is very bad for precision putting. The new technology Quantum Symmetric Golf Putternever twists upon impact and that makes it clearly superior to the old blades and mallets.
Polar Symmetry is a principle of physics, spherical geometry, and vector analysis that is far beyond the interest level of most people, but it is nevertheless extremely important for golf putter designers to understand. Fortunately for most of us ordinary folk, this complicated principle can be made simple by analogy.
Wobble Test -- Hold the golf putter between the palms of your hands as shown, and then move your palms forth and back as if you were testing the straightness of a pool cue. If the putter head wobbles as you do this, then it lacks polar symmetry and will always suffer stroke wobble when in actual use out on the green -- that of course is very bad for precision putting. The new technology Quantum Symmetric Golf Putternever wobbles and that makes it superior to all the old blades and mallets.
The symmetry (or lack thereof) is easy to demonstrate. The "Tap Test" demonstrates a putter's propensity for detrimental impact twist, and the "Spin Test" demonstrates propensity for detrimental stroke wobble.
Now you know more about the principle of polar symmetry than most people, in fact you know more about golf putter design, than all the Blade/Mallet Designers put together,
There are two Golf Putter Technologies: Symmetric and Asymmetric.
One is effective for golf putting performance; the other is defective.
