While the padlock’s tiny hole feature was once revolutionary, weatherproof padlocks are also on the market. This design ensures a padlock will continuously ensure your belongings are safe all year round.
Another Reason for the Padlock Design
In addition to safety from rusting, the tiny hole on the bottom of a padlock fulfills another important role. Sometimes, the padlock may become stuck or unable to open, even with a key or correct code. As such, the hole can be lubricated synthetically to help the padlock pop open.
Other Everyday Things With ‘Hidden Features’
Padlocks aren’t the only thing that has been designed with secret or hidden features. Here are a few other handy items that serve multiple purposes.
Screwdrivers as Wrenches
Knowing how to work on cars is a helpful skill, especially with the rising number of vehicles on the road. Yet most mechanics agree that working on cars can be tough because of the small space and crevices that must be maintained. Fortunately, most screwdrivers can be slid into a wrench to help reach those small spaces.
Color Swatch on Clothes
Clothing once came with a color swatch. While some still do, depending on their quality and materials, few people know why. There are a few reasons. First, these swatches make it easy to color-match fabrics or threads when clothing becomes ripped or damaged. Moreover, these color swatches can be used to test how certain products, like laundry soap, will impact the item’s color. Essentially, those little swatches are a tester piece of fabric that matches the outfit, so the buyer will know how to properly care for their clothing.
