It turns out a lot of people do.
These are all items voluntarily surrendered at the security check at the Greater Binghamton Airport.
Knives, larger chains, tasers, and tools longer than seven inches aren't allowed as carry-ons.
If you realize you have a prohibited item at the checkpoint, you have several options.
You can put it back in your vehicle, give it to someone else with you, mail it home or to your destination from the airport, put it in your checked baggage or voluntarily surrender it to the TSA.
"If you're not sure, TSA has an app for that. It's called my TSA and so what happens is it says Can I Bring My... you type in the item and immediately it will let you know if you can put it in your checked baggage, carry on baggage, either or neither. You can find that out 24/7," said Lisa Farbstein, TSA spokeswoman.
You can download the app for your mobile device for free from the website TSA.gov, or you can just use the question tool on the website.
