Seems like this isn't only an example of Gurkha effectiveness, but also how traveling with your tools of defense is useful to society.
From Second City Cop.
•[Gurkha] soldiers have long been known the world over for their valor and these khukuri-wielding warriors winning the British many a battle have become folklore.
A retired Indian [Gurkha] soldier recently revisited those glory days when he thwarted 40 robbers, killing three of them and injuring eight others, with his khukuri during a train journey. He is in line to receive three gallantry awards from the Indian government.
•“They started snatching jewelry, cell phones, cash, laptops and other belongings from the passengers,” Shrestha recalled. The soldier had somehow remained a silent spectator amidst the melee, but not for long. He had had enough when the robbers stripped an 18-year-old girl sitting next to him and tried to rape her right in front of her parents. He then took out his khukuri and took on the robbers.
