A correction. Perhaps the Russian "Butterfly" mine was not designed as a "disguished toy". However, the result was petty much as if it had been.
http://www.un.org/Depts/dpko/mine/country/afghanis.htm "The most infamous mine used during the Soviet Union's occupation period was the so-called 'butterfly' mine. Helicopter crews dropped untold numbers (figures range into the millions) of the small mines from the air. They were designed to flutter to the ground without exploding,
and to thousands of children they resembled butterflys or toys. But one wing of the mine was filled with liquid explosive, designed to ignite and explode on contact, severing hands.
