"Wanna bet?"

You lose the bet. Here is the link to "prohibited and permitted items." Nail clippers are expressly permitted.

Nail clippers are expressly permitted.

Last time I was at the airport, they were permitted if and only if they did not have any sort of attached nail file. Since most clipper I've seen do have such an attached file, they would be prohibited unless such file was broken off.
