Today, the shape of golf shafts is made of various contour such as bubble, steps, flare and rocket.

From the engineering points of manufacturing and producing a golf shaft;

• The weight of the shaft is controlled by the amount of material used in production. That is where the current availability of a light/heavy steel or graphite shaft. But the amount of material used will also have an effect on the strength of the shaft. This is why manufacturers can’t produce a 60 grams steel or 30 grams durable graphite golf shaft.

• The strength of a composite shaft can be made with difference pregreg such as aramid-fibers, boron, fiberglass. Ceramic, Kevlar and binding resin agents. For steel is amount of carbon, chromium, etc..combination with iron ore.

• The flexibility of the shaft is control by the thickness of the shaft’s wall.

• The torque of the shaft is control by shaft’s diameter regardless of steel or composite materials

Now, shaft designers will able to manufacture on the difference part of the shaft’s properties by using various materials type and density to produce the desired distribution of the weight; flex and torsional stiffness.

From The Clubmaker’s analysis by Golfsmith, The golf equipment industry clearly proved that improvement in accuracy and control cannot be made at the expense of proper feel for stiffness and over crispness. Designers are finding the rate of taper is a significant contributor to a shaft’s overall solid feel and performance. For example, among the big tip shaft tested, shafts of the same larger tip diameter revealed completely different feel and performance results.

It cannot be said simply choosing one specifically larger tip diameter ensures a good performing shaft. And, it may soon be discovered the real secret to success with the big tip shaft will be in how the tapers in outside and inside diameter before it gets to that larger diameter.

Whether the difference contour of the shaft technically designs is really of a marketing and cost saving move by shaft companies or really a performance enhancement is still up in the air.
