A post on Facebook has gone viral of late sharing one man’s story about how he came to learn about the purpose of the hole.

The post reads: “My mother-in-law couldn’t stop laughing when she realized I had no idea what the tiny hole in a nail clipper is for. Now I wonder… am I the only one who never knew?

“I was so embarrassed — I’d literally never thought about it before.”

While you’d possibly presume that people with ridiculously long nails are inviting gross bacteria into their lives, Kayla Newman, a nail tech based in North Carolina, insists that in years of working her clients have never had ‘nasty nails’.

“Generally people who have long nails know how to maneuver with them and keep them clean,” she said.

“If you’re spending upwards of $60 to get your nails done and you don’t keep them clean, that doesn’t make sense.”
