Support BladeForums! Paid memberships don't see ads! From what I've read in several places, scissors less that 4 inches is allowed by TSA in carry on. Nowhere I've looked clarifies if this is blade length or overall length. My wife wants to take a hair cutting scissors blade length less than 4, overall length more than 4. Post a link if you have one, otherwise don't reply if you don't know for certain. It's a domestic flight, not international if that matters. Thanks for any help.
