Additionally, the hole acts as an anchor point , preventing the needle from coming loose from its base and ensuring the pin stays closed even if it’s subjected to pressure or movement. In other words, that little detail is what makes the safety pin truly secure .
Helpful tips for making the most of safety pins
Always have several sizes on hand: small ones are ideal for underwear or fine sewing, while large ones are good for blankets, backpacks, or thick clothing.
Clean them occasionally: they can rust with use. Wipe them with a cloth soaked in vinegar and dry them well to prolong their lifespan.
Keep them closed: avoid punctures and protect the tip from losing its sharpness.
Use them as a tool: you can untangle chains, open stuck zippers, or improvise a pendant or brooch.
The safety pin, that little sewing-box hero, proves that even the simplest objects can have clever engineering behind them. Knowing what a hole does not only satisfies our curiosity, but also reminds us of the ingenuity of those who designed practical tools we still use today.
