Nail clippers may seem like a simple tool, but the small round hole at the end actually serves multiple practical purposes. Its most common use is for attaching a keychain, ensuring your clippers stay secure, portable, and less likely to be misplaced—especially handy when traveling. Some models come with a small chain for this,

though attaching the clipper directly to a keyring is often stronger and more reliable. Beyond storage, the hole can also be surprisingly useful for small household tasks. By placing a thin wire through it, you can safely bend or shape the wire without risking cuts or scratches to your fingers. The hole can also help guide delicate cords, threads, or yarn for precise trimming, giving you more control than cutting by hand. While many people overlook it, this little hole adds versatility, transforming a basic grooming tool into a multifunctional helper that’s useful not only for nail care but also for everyday problem-solving around the home.
