Length of rod, bent. 
This is a short length of rod, about 2 inches long and 5/16 inch diameter, obviously nipped off at both ends with some bolt butters or a sheer.  It's fairly heavy, but not otherwise impressive compared to the same thing out of steel.  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 it is pure tantalum within the detection limits of the machine.
