Tear Gas Makes Weapon of Fountain Pen
AN INNOCENT-APPEARING fountain pen containing a charge of tear gas which makes it a most effective weapon has been perfected for the use of cashiers, bank tellers, and others likely, to be objects of robbery. The tear gas is carried in the pen in liquid form and when the trigger is released it spouts out of the pen as a vapor which will blind and disable anyone it is directed against. The release trigger is shaped like the conventional ink-filling lever, and in appearance the weapon cannot be distinguished from an ordinary writing tool.
