Iron Golf Shafts – KBS TOUR V

When we get back to back wins 2013 in the Scottish Open and the British open the shaft in the bag of the Phil Mickelson gets a lot of attention. Well, it turns out it was it a tour prototype that is now available. It is an unusual profile for steel but not unique. Here is a look at the KBS Tour V which now is the stock steel shaft in the 2014 Callaway Apex Pro Irons. It has a long handle, every so gently declining in stiffness until the about 14″ from the tip. Then it declines rapidly. I have heard Kim Braly refer to the design as ‘fast tip.’

It is noteworthy to mention that the stock graphite in the 2014 Callaway Apex Pro is the UST Recoil. An interesting choice of premium shafts, in a classy players design iron head.

Within the golf club fitting and building community there are now three methods to understand bend profiles of shafts. A future technical article will discuss the history and methods of the systems. The 3 point bend system used in these reviews is classical textbook engineering for beam measurement. It is the language spoken by the vast majority of golf shaft designers and engineers. That is why I built the Fit2Score software around this measurement methodology.

I tested a review sample installed in a Miura CB-501 on the range and was surprised at how tight my ball flight dispersion was. I had expected more variation from the soft tip. That was not the case, the balls were flying true despite a heavy cross wind the day I was testing. As with any golf shaft, you will not know if it is right for your swing without testing it.
