It's unlikely, but if there could be anything worse than the Breast Ripper, it is surely the Pear of Anguish. This was a pear-shaped device, with the body of the pear made up of four metal "leaves" joined by a hinge at its top, and a key or crank on one end. The pear was inserted into the vagina, anus or throat, depending on the nature of the crime committed: The oral device was reserved for heretics, while the anal and vaginal pears were used on homosexuals and witches, respectively. Turning the key opened the leaves, causing massive internal damage [source: Medieval Times & Castles]. The device was rarely fatal, but other methods of torture would usually follow.
