I fly alot for work. I use circular knitting needles and I sometimes carry small snips. I make SURE the blades are less than 3" just to be safe (less than 4" is required by TSA) . I try to leave the scissors in my checked bag and use a thread snip in my carry on - and I LOVE the idea of the dental floss container - thanks Lady Elisabeth!
