Nail clippers are a simple household tool mainly designed for trimming nails, but their small round hole at the end actually adds a bit of unexpected versatility. One of its most practical uses is attaching a keychain, allowing you to keep the clippers with your keys so they are less likely to get misplaced and are always within easy reach.
Another handy function of the small hole is helping with bending wire. By threading a thin piece of wire through the opening, you can gain better control and leverage than you would using your fingers alone, making small adjustments much easier.
Nail clippers can also serve as a makeshift tool in certain situations. Parts of the clipper may help tighten or loosen very small screws when no proper screwdriver is available, although they should not be considered a replacement for the correct tool.
In addition, the pointed edge of the attached nail file can be useful for opening packages by cutting through tape on boxes or envelopes. While nail clippers are best known for nail care, these extra functions make them a surprisingly versatile everyday item that can come in handy for a variety of small tasks.
