With golf putters, the short answer is Polar Symmetry. It enables Sweet Impact, and sweet impact is a requirement for precision putting. It is what every golfer needs on the putting green, but amazingly, very few golf putters embody it. This is the Big Idea that makes a good golf putter better than the bad putters.
Imagine you are a tennis player - Would you choose to use a center shafted racquet or a side shafted racquet? Of course you'd choose a center shafted racquet. In fact choosing a side shafted racquet would be so stupid that nobody even makes one!
Imagine you are a baseball player -- Would you use a straight bat. or one with an off-set? Obviously, you would always use a straight bat. In fact using an off-set bat would be so stupid that nobody even makes one!
Imagine you are a pool shooter -- Would you use a pool cue that is straight, or one that is bent? Of course you would use the most perfectly straight cue you could find in the rack, and you would test it by rolling between your palms for wobble before using it. It would be stupid to use a pool cue that is bent out of shape, in fact so stupid that whenever a cue becomes warped even just sightly, it is always tossed out.
What do all these useless tools have in common? They all lack the Polar Symmetry required for Sweet Impact. Of course sweet impact is a requirement for precision putting. QUANTUM GOLF PUTTER has it while others lack it.
Without Sweet Impact, a golf putter is unsuitable for putting. People intuitively know this, and they can feel it, but most really do not understand what enables it. What enables Sweet Impact is the principle of physics known as Polar Symmetry. A golf putter has Polar Symmetry when it has a symmetrical grip on a straight and sturdy shaft that vectors precisely into the center of mass of a compact. massive, and symmetrical head.
Lacking Polar Symmetry makes a golf putter incapable of Sweet Impact and that makes it unsuitable for precision putting. It's easy to test your golf putter for this.Just do the quick and easy TAP TEST and SPIN TEST -- if your putter fails either test, it lacks polar symmetry and should be tossed in the trash heap of defective design.
QUANTUM GOLF PUTTER passes both tests; typical Mallets and Blades fail miserably. This is the 1ST and most important of 48 reasons why Quantum is the Better Golf Putter.
SPIN TEST -- Hold your putter shaft between the palms of your hands as shown, and then move your palms back and forth to rotate the shaft to and fro (as you would do when testing a pool cue for playing suitability). If there is any wobble, then your putter lacks the required polar symmetry for sweet impact, and it should be tossed into the trash heap of defective design.
Other golf putter makers may claim their putters have sweet impact; some even claim their putters have a "large forgiving sweet impact area" but that is all marketing hype. First of all, the truth is that a sweet spot is a spot not an area, and secondly, any golf putter that lack Polar Symmetry cannot have a Sweet Spot in the first place. Unscrupulous marketeers are trying to make you believe something that anyone with any knowledge of physics and tool mechanics would know to be untrue. Don't be fooled! There is one golf putter that embodies the Big Idea of Polar Symmetry and Sweet Impact -- QUANTUM GOLF PUTTER.
TAP TEST-- Hold your putter loosely with one hand as shown, and then with a finger of your other hand tap the place where you usually strike the golf ball. If the putter head twists when tapped, it does not have the polar symmetry required for sweet impact. and it needs to tossed into the trash heap of defective design.
