Most people use nail clippers without giving much thought to their design, but that tiny round hole on one of the handles actually serves a practical purpose. While it may look decorative, it was created with functionality in mind. This small detail helps turn a simple grooming tool into something much more convenient for everyday use.
The primary purpose of the hole is to allow the clipper to attach easily to a keychain, lanyard, or small metal ring. This keeps the clipper accessible and prevents it from getting lost in drawers or bags. By threading a small key ring through the hole and clipping it to your keys or a hook, you ensure the tool is always within reach.
