Have you ever noticed the little hole on your nail clippers? It’s not there by accident; it has a very specific purpose that almost no one knows about. Let me explain what it’s for.

Assembly aid (trade secret)
During the manufacturing and electroplating process, this hole is used to hold or suspend individual parts. This allows machines or workers to easily and without leaving streaks on small pieces of metal.

Pin locking mechanism (on some models)
On some types of pliers, this hole provides stability. When the handle is rotated into the working position, the hole is caught by a small protrusion or pin, preventing the handle from swinging sideways during cutting.

Do you have any of these reasons in mind, or do you know of another clever application that I missed? I look forward to hearing your ideas!
