Padlocks come in many shapes colours and sizes. They have been around for hundreds of years, ranging in complexity of design by different people and civilisations depending on the technology and manufacturing processes they had available. With the industrial revolution came the mass-produced padlock which eventually settled on a pin tumbler design. Called so because inside are some pins and a barrel which rotates or tumbles over.
