Why it’s useful: Nail clippers are small and easy to lose. Attaching them to something larger (or something you already carry) ensures you always have them when you need them.
Pro tip: Use a small split ring (like the kind on keys). Don’t use a large ring that will flop around and get in the way.
5. To Identify the “Bottom” Blade (Assembly/Direction)
This is a less common but interesting use. LongDistance Bus & Rail
The purpose: In some nail clipper designs, the hole helps you identify which blade is which during assembly or cleaning. The bottom blade (the one with the hole) is the stationary blade. The top blade (attached to the lever) is the moving blade.
Why it matters: If you take your clipper apart for deep cleaning, the hole helps you reassemble it correctly.
