The "small round hole" on the nail clipper has special and effective uses!

1. Turn it into a key ring:
The small hole is the perfect size for threading a key ring through. Simply thread your key ring through, and your nail scissors will stay securely attached – no more annoying searching in your bag or losing them in your pocket.

Some hair clippers even come with a short chain already attached to the keyring, but this can easily come loose. For a more secure hold, you should remove the chain and thread the keyring directly through the hole. This way it's sturdy, compact, and always within easy reach when you need a quick haircut.

2. Effortlessly bend or shape wire:
Need to bend a stiff wire – like a paper clip, cable tie, or craft wire – but don't want to hurt your fingers? Insert the wire into the round opening and use the side cutters as a lever. The metal frame provides the necessary leverage and control, allowing you to shape the wire with minimal effort – without risking cuts or sore fingertips.

This trick is especially useful for DIY projects, jewelry making, or even for straightening bent earring posts.
