"Personal flamethrowers" marketed to the general public

A flame-thrower that can hurl a stream of fire half a metre long is being marketed in China to help women fend off unwanted advances.

The device is being billed on shopping websites as a must-have "anti-pervert weapon" that can be discreetly carried in a ladies’ handbag.

Some are shaped like a cigarette lighter and emit small flames, while others hurl fire for 50cm with temperatures of up to 1,800 degrees Celsius (3,300 Fahrenheit).
