That Little Hole in a Safety Pin Isn’t Just for Looks—Here’s What It’s REALLY For

Next time you look at a safety pin, take a moment to notice the small hole near the head of the pin. It may seem like a simple design feature, but it’s actually there for a very practical reason.

The tiny hole serves as a place to attach a string or thread to prevent the pin from accidentally opening. This makes it especially useful when sewing or in emergency situations where extra security is needed. By threading a piece of string or floss through the hole and tying it, you create a backup that ensures the pin stays closed, even under pressure.

In fact, this design is particularly useful for holding fabric together temporarily during sewing or for keeping bandages in place. So, that small hole isn’t just decorative—it’s a clever feature that adds both safety and utility to an everyday object.
