Small grooming tools.
Eventually, the nail clipper disappears.
A small opening can provide a straightforward solution.
If the clipper is attached to a ring or holder, it becomes easier to keep it in a designated place.
For people who travel frequently, this can be particularly useful.
A grooming kit can contain several small objects that are easy to lose.
Keeping tools attached or organized reduces that problem.
In this sense, the hole isn’t mysterious at all.
It is simply an example of practical product design.
Don’t Confuse the Hole With the Lever’s Pivot
Another reason people become confused about nail-clipper openings is that the tool contains several small holes and connection points.
The lever itself has to be attached to the clipper body.
The moving components must be aligned correctly so that the lever can transfer force to the cutting jaws.
A pivot or attachment point may look like a small hole, but it serves a very different mechanical function.
