for the tool’s functionality. The coil isn’t just there for aesthetics—it stores tension, which is essential for keeping the pin securely closed when not in use.
Without this tension, a safety pin could spring open unexpectedly, potentially causing injury or failing to hold materials together. That small coil, reinforced by the tiny hole, ensures stability, flexibility, and longevity, making the pin a quietly brilliant piece of everyday engineering.
So, What Exactly Is That Tiny Hole For?
Here’s where the story gets truly interesting. That small hole at the base of
