The hole also has other clever uses. You can hang your clipper for quick access, slip a finger through it for extra grip when trimming tough nails, or even keep fingernail and toenail clippers together on one ring.
This feature isn’t new either. Early nail clippers from the late 19th century included the hole so people could carry their grooming tools easily—long before modern bathrooms were common. That tiny hole proves something simple: small design details can make everyday tools far more practical.
