Pro wrestler-turned-yoga guru Page Falkinburg, known to fans as Diamond Dallas Page, sued rapper Jay-Z and Roc-A-Fella records in December 2005, claiming Jay-Z had stolen his signature diamond-shaped hand sign. Falkinburg uses the sign as a motivational speaker, author and yoga instructor, says his lawyer, and Jay-Z's use of the "Diamond Cutter" is diluting the trademark.
