What the Small Round Hole on Nail Clippers Is Designed For

That small hole has a simple purpose: keeping nail clippers easy to find. It allows them to attach to a keychain, lanyard, or hook so they stay visible, dry, and within reach instead of lost in a drawer. Some people also use it for better grip, to hang them in the bathroom, or to link multiple clippers together. First appearing in late-19th-century designs, this small detail has lasted because it quietly makes everyday life more convenient.
