Safety lock: Some nail clippers use the hole as part of a locking mechanism. You can insert a small pin or rod into the hole to keep the clipper closed. This prevents accidental cuts or injuries when storing the clipper in a bag.
Innovative Uses: Creative users have discovered other uses for the hole, such as threading thin wire through the hole to use the wire cutters as a makeshift tool for crafts or small repairs.
3. Why Many People Overlook This Feature
The widespread ignorance about the hole’s purpose can be attributed to several factors:
Lack of instructions: Most nail clippers are sold without detailed instructions or explanations of their design features. Therefore, users rarely wonder about the purpose of the round hole.
Ease of use: Nail clippers are simple tools that require no prior knowledge or special skills. Most people use them only to trim their nails and never explore their additional features.
