I flew to N.C. to visit my parents. I just called the airline, and called the security dept. at the aiport. It was O.K. I did bring plastic and I'm sure wood would be fine, but not a cutter. Just call both, and look online for policies. You can print up the policies if it says they allow it and then there will be no questions at the gate.
Imagine that long with NO KNITTING!!!!I would go crazy!!
