Why there is a restriction on carrying a Swiss Army knife?

Swiss army knife is restricted on a carry-on bag due to the following reasons:

  • It’s a deadly weapon. If you’re trying to take your trusty pocketknife on your next flight, keep in mind that the TSA deems it a deadly weapon and may not allow it through the checkpoint.
  • It’s too big. If your swiss army knife falls into the category of “too big,” airlines may not be able to accommodate it in your carry-on bag. Make sure to check the size limits for each carrier before packing!
  • The blade of your knife cannot be longer than 2.36 inches (6 cm).
  • It can be used to harm others.

Check with Your Airline’s Policy

Some may allow small folding knives, but not larger knives. Check the airline’s website or call ahead for specific information.


There is no definitive answer to this question – every airline has different rules, and sometimes they are not clearly spelled out.

That said, I would recommend avoiding bringing a Swiss army knife on a plane as it can cause a lot of inconvenience for other passengers.

If you absolutely must bring your Swiss army knife on board, make sure to keep it in its original case and avoid bringing it into the cabin.
