10. Poisoned Dart Pens
During World War II, the Special Operations Executive (SOE) developed covert weapons for agents operating behind enemy lines. One such device was a pen-shaped weapon capable of firing poison-tipped darts at close range. Lightweight and easily concealed, these pens offered agents a last-resort defense during undercover missions. The darts were designed to deliver a lethal dose of poison, ensuring rapid incapacitation of the target. This innovation exemplifies the SOE’s commitment to equipping operatives with specialized tools for clandestine operations. (iwm.org.uk)
