  Golf club. 
Considering the number of items that claim to be made of titanium but are not, I bought this cheap golf club purely on speculation.  I would have been perfectly happy to report that it was yet another titanium fraud, but actually analysis by x-ray fluorescence spectroscopy at the Center for Microanalysis of Materials, University of Illinois (partially supported by the U.S. Department of Energy under grant DEFG02-91-ER45439) indicates that it is virtually pure titanium!  Score one for cut-rate discount golf clubs at SAMS Club.
