The Spear of Longinus displayed in the Imperial Treasury at the Hofburg Palace in Vienna, Austria. At the core of the spear is the original blade, now broken, and combined with an iron pinion that is reputed to be a nail taken from the cross - the "spear of destiny" grants victory in battle to the wielder.
The infamous spear of destiny, or Holy Lance. Allegedly the spear which pierced Jesus's side as he was crucified. Myths attribute to the lance special powers, for which Hitler was desperately after and the reason why he started WWII. Once acquired it, losing it means death. As the US seized it at the end of the war, Hitler apparently committed suicide upon losing it.
