No, you can’t carry it as a carry on. While you might slip through, if you are caught you might miss your flight, depending on who catches you and what their attitude is. I have flown many times with my bow packed in a properly protected case and have never had any problems, other than sometimes TSA doesn’t put it back in the case the way I would like it. One time it didn’t come up on the baggage carousel when I arrived and I got worried that it was lost, but a baggage worker came out with it separately, saying he wanted to make sure it got picked up by the right person. Also, I would never show anyone a handmade stone knife on an airplane. You never know when someone walking down the isle would see it, nervously report it to the airline employees, and the next thing you know you have been diverted to Chicago or some place and are being hauled off the airplane by the cops.
