There are some cork screws out there that one could do some major damage with, but they're now allowed in your carry-on.
Cuticle clippers, eyelash curlers, tweezers and knitting needles are all ok. No pointy scissors of any kind are allowed.
Leave your fancy propane burning cigar and pipe lighting torches at home and don't buy one on vacation. They won't allow those even in your checked baggage. Those things cost $30 to as much as $400 and TSA will make a passenger surrender it. I saw one guy almost go nuts when TSA confiscated his $400 torch. At least they left him his cigars. ;)
A passenger can only carry-on 2 'Bic' lighters and 4 books of matches. The extras are confiscated.
No tools allowed in your carry-on, nada, none, checked baggage only, unless it's for a prosthesis.
I hope this helps. Keep in mind that this could all change next week, though. ;^)
Can they be mailed, sans fuel?
