The Real Reason Your Nail Clipper Has a Small Round Hole

This makes it especially useful for travel, gym bags, or busy households where small items often go missing. Beyond keychains, the hole can offer several bonus uses. Some people hook the clipper on a bathroom organizer for quick access. Others find that slipping a finger through the hole provides a steadier grip, especially when trimming hard-to-reach nails. You can even attach multiple clippers to one ring to keep fingernail and toenail tools together.
