Padlock

Everything is secure with a padlock.

Padlocks are security devices used to keep items secure, that can usually be opened via a code or key, and are portable.
Padlocks commonly have a cylindrical ‘U’ shaped top, called a shackle, typically attached to a rectangular base or body, and sizes vary greatly, with different sizes used on proportionate objects.
To use a padlock, the shackle is placed over or through a latch, and the shackle is then closed.
Padlocks have been used for thousand of years by Ancient Egyptians and Babylonians, and they were in use from 1000 BC in Asia’s China, and they became more widespread via travelling merchants.
Padlocks are typically made of steel or brass, or a combination of both, and they were originally made from wood, although silver, brass and bronze were later used.

A ‘padlock’ is said to have been named so, between the 9th and 11th century, when the invention was used to secure paddocks.
In the 1800s, padlocks become more commercially viable, were manufactured in mass production processes, and the security of the locks were improved.
Padlocks typically are locked by the shackle catching on an internal mechanism in the body of the device, and they are often self-locking by a person pushing the shackle closed, but occasionally they require a key for assistance.
Padlocks are often unlocked by using a key or entering a number or letter combination, and they can be illegally unlocked by using a lock pick or a heavy tool, such as a hammer, chisels or bolt cutters.
Pictures of padlocks are used as a popular symbol for securing, and are used universally on the internet and online world.
