Josef Mengele's Scalpel

Mengele was a Nazi scientist that worked at the Auschwitz concentration camp and did human experiments on camp inmates, specifically twins. He was appropriately nicknamed the 'Angel of Death'. The scalpel would only take effect when two or more people were cut by it and they were nearby each other. Cuts made by the scalpel will heal like any other, regular cut. When people that were cut by the scalpel are near each other, their wounds will reopen because they were not permanently healed. When next to a person who's been cut, those two people 'heal'. If, for example, one person was cut on the forearm and another on the wrist, those wounds would open and connect with each other to heal. Mengele's methods of researching twins was imbued into the scalpel, and it essentially creates siamese twins and gives a new meaning to the phase 'chain gang'. Was taken by the Allies when they liberated the concentration camps and promptly handed over to the Warehouse.
