There are still people who do not know the use of this small hole

A padlock is a common item that serves a major purpose.

People use them for their bikes, outdoor sheds, toolboxes, and gates.

They’re designed to withstand the elements and attempts to damage or cut them.

However, they have a secret feature, a small hole on the bottom,

that also serves a major purpose. Using a padlock is one sure way to keep your belongings

safe from being stolen. They’re a small but impactful tool, made of metal. As a result,

padlocks are susceptible to rusting from water damage and extreme weather conditions.

Fortunately, they’re designed with a tiny mystery hole on the bottom, that allows water to escape.
