I'm wearing braces and will spend a few months in another country. In order for my treatment not to be interrupted, my orthodontist will give me a few wires which look like this:
Is there any chance of them not being allowed in hand luggage? (The edges are quite sharp.)
Might be of relevance: I'll be flying from Europe to the US.
ADDED: I don't need them during the flight but I don't want to check them in, since in case they'd be examined without me (e.g. if TSA opens my suitcase), any slightest bending would invalidate the whole setting and make them useless.
