💅 Nail clippers

Nothing — nail clippers sail through security without any issue. They are permitted in carry-on baggage in all regions, and screeners will not stop you for them.

No. Nail clippers are universally permitted in carry-on and checked baggage across all regions. Even the small attached nail file is not classified as a blade and is allowed through without restriction.

This is extremely rare. The TSA and equivalent agencies in other regions explicitly permit nail clippers, including the nail file, and officers are trained accordingly. If your bag is searched for an unrelated reason and clippers are spotted, they will simply be noted and cleared.

There is no security reason to put nail clippers in checked baggage — they are fully permitted in carry-on. Keeping them in your toiletry bag in carry-on is the most practical approach.
