I don't think anyone accepted that when I pointed it out a couple of years ago. It is, however the case. > Carbon fiber is lighter than both steel and titanium, and considerably > more rigid than either metal. Not exactly. Carbon fiber is considerably more flexible than either titanium or steel. It's very high resistance to both compression and stretch at the extreme fiber of the section assembly can make the assembly more rigid for a given section than either steel or titanium. Flexibility can be controlled to some degree with fiber orientation in the matrix, as well as section dimensions. Steve's carbon tube has an enormous section diameter, so it's going to be the stiffest hammer shaft on the planet. Remember that the first iteration used aluminum tubing, and was still way stiffer than conventional steel shafted hammers just because of the section size. >I've also heard > people insist that titanium is more rigid than steel or carbon fiber. > That is simply false. > > Mark Purney, RPT It is indeed, verifiable by looking it up. The problem I see is more in a belief of some sort of universal superiority of a material than attempting to understand how it's individual properties perform in a specific configuration and use.
