As my imminent trip nears, I consider all of the things necessary before I depart. Packing, for one, would probably be a good idea at this point.
I intend to bring three bags: 1) the one checked bag that I am allowed, under 50lbs with everything I can manage in it; 2) one carry-on bag (my "purse") with my laptop, a novel (John Steinbeck's East of Eden) and some essential documents; 3) one carry-on with yarn and needles.
Now, that said, I decided to check one more time and make sure the international airlines don't have any restrictions against knitting needles. For a while now, they've been accepted on planes here. I'm flying Lufthansa and they have no issue with knitting needles and say specifically that they are acceptable items to carry on-board.
I was curious, though, to see what else I could find about knitting needles on planes. I came across a thread in which a person asked why knitting needles are accepted on planes, as they are sharp and thus deadly.
This person has clearly never touched a knitting needle before. You have to get pretty small before they get sharp. How sharp? Approximately as sharp as a dull pencil. Most knitting needles small enough to puncture the skin are double pointed (they are equally pointed on both ends), so if you're gonna stab someone with it, you have to push on the opposite sharp end with your hand or a finger. If you give it enough force to puncture someone else, you've given it enough force to puncture yourself and that just seems counter-intuitive.
As a matter of fact, being punctured by something just hurts for a second, it isn't deadly. People have been impaled by huge stuff and walked into the emergency room with it.
In short, people shut up about knitting needles on planes unless you're ready to give up your pens, pencils, styluses, long fingernails, most earrings and lots of other kinds of jewelry, chopsticks, and anything else that's long and slender and "sharp".
