Swiss Army Knife, a Sub-Machine Gun, Body Armour, and a Laser Sight

S1 E14: An iconic knife that's been an integral part of military culture for more than a hundred years, the Swiss Army Knife has been put in service around the world - and even in space. In a factory in the Swiss Alps, a machine exerting 40 tonnes of force punches the blades from strips of steel forged with chrome - a legendary blend which ensures a clean cut and a tool that'll last a lifetime.
