What’s the Small Round Hole on a Nail Clipper For?
That little round hole near the end of many nail clippers is usually part of the clipper’s construction, and it can have a couple of practical purposes.
-
Hanging/storage: On many clippers, the hole lets you hang them from a small hook, key ring, or storage loop.
-
Manufacturing/design: The hole can also be part of how the metal components are assembled or shaped.
-
Not usually a sharpening feature: Despite some online claims, it’s generally not designed to sharpen the nail clipper.
If you’re referring to the larger circular opening near the cutting jaws, that’s a different feature. A photo of your nail clipper would let me identify exactly what that particular hole is designed for.
